Pro Works in terminal over SSH
Unlike other editors such as Sublime Text, Vim is a command line editor and hence can be used in remote development environments like Chromebooks via SSH.
Pro Extremely portable
Vi/vim exists on almost all Unix-like platforms. It's the de-facto Unix editor and is easily installed on Windows. All you need to make it work is a text-based connection, so it works well for remote machines with slow connections, or when you're too lazy to set up a VNC/Remote Desktop connection.
Pro Keyboard-based, mouse-free interface, and trackpad support
There's no need to reach for the mouse or the Ctrl/Alt buttons again. Everything is a mere key press or two away with almost 200 functions specifically for text editing. Vim does support the mouse, but it's designed so you don't have to use it for greater efficiency.
Versions of vim, like gVim or MacVim, still allow you to use the mouse and familiar platform shortcuts. That can help ease the learning curve and you'll probably find you won't want to (or need to) use the mouse after a while.
Pro Lightweight and fast
When compared to modern graphical editors like Atom and Brackets (which have underlying HTML5 engines, browsers, Node, etc.), Vim uses a sliver of the system's memory and it loads instantly, all the while delivering the same features. Vim is also faster than Emacs.
Pro Free and open-source software
Vim is open-source, GPL-compatible charityware.
Pro Macros increase productivity
Many text editors have programmable macros, but since Vim is keyboard-based, your programmed macros are usually far more predictable and easier to understand.
Pro Usable from a Terminal or with a GUI (GVim, MacVim)
If you happen to be logged into SSH, you can use Vim in a terminal. It can also run with a GUI too.
Pro Great productivity
Vim's keyset is mainly restricted to the alphanumeric keys and the escape key. This is an enduring relic of its teletype heritage, but has the effect of making most of Vim's functionality accessible without frequent awkward finger reaches.
Pro Once learned, it's very hard to forget
Vim's somewhat steep learning curve is more than made up for once you've mastered a few basic concepts and learned the tricks that allow you to program faster with fewer cut/paste mistakes.
Pro Everything is mnemonic
No need to memorize different key combinations for things like deleting the text inside of a block or deleting the text inside of a pair of quotes. It's just a series of actions, or nouns and verbs, or however you prefer to think about it. If you want to delete, you select "d"; if you want it to happen inside something, you select "i"; and if you want the surrounding double-quotes, just select ". But if you were changing the text, or copying it, or anything else, you'd still use the same "i" and ". This makes it very easy to remember a large number of different extremely useful commands, without the effort it takes to remember all of the Emacs "magic incantations", for example.
Pro Tons of plugins/add-ons
This makes Vim the definitive resource for every environment (Ruby/Rails, Python, C, etc.), or simply just provides more information in your view.
Pro Has multiple distinct editing modes
Interaction with Vim is centered around several "modes", where purpose and keybindings differ in each.
Insert mode is for entering text. This mode most resembles traditional text entry in most editors.
Normal mode (the default) is entered by hitting ESC and converts all keybindings to center around movement within the file, search, pane selection, etc.
Command mode is entered by hitting ":" in Normal mode and allows you to execute Vim commands and scripts similar in fashion to a shell.
Visual mode is for selecting lines, blocks, and characters of code.
Those are the major modes, and several more exist depending on what one defines as a "mode" in Vim.
Vimtutor is an excellent interactive tutorial for people with no prior experience of Vim. It takes about 30 minutes to complete.
Pro Excellent performance
As it loads the whole file into RAM, replacing all string occurrences in 100 MB+ files is quick and easy. Every other editor has sort of died during that. It is extremely fast even for cold start. Vim is light-weight and very compact. In terminal, it only uses a small amount of memory and anytime you invoke Vim, it's extremely fast. It's immediate, so much so you can't even notice any time lag.
Pro Can never outgrow it
The fact that very few, if any, people claim to be a "Vim Master" is a testament to the breadth and depth of Vim. There is always something new to learn - a new, perhaps more efficient, way to use it. This prevents Vim from ever feeling stale. It's always fresh.
Pro Productivity enhancing modal paradigm
As with all vi-like editors, Vim provides a modal paradigm for text editing and processing that provides a rich syntax and semantic model for composing succinct, powerful commands. While this requires some initial investment in learning how it works in order to take full advantage of its capabilities, it rewards the user well in the long run. This modal interface paradigm also lends itself surprisingly well to many other types of applications that can be controlled by vi-like keybindings, such as browsers, image viewers, media players, network clients (for email and other communication media), and window managers. Even shells (including zsh, tcsh, mksh, and bash, among others) come with vi-like keybinding features that can greatly enhance user comfort and efficiency when the user is familiar with the vi modal editing paradigm.
Pro Built-in package management
Starting with Vim 8, a package manager has been built into Vim. The package manager helps keep track of installed plugins, their versions and also only loads the needed plugins on startup depending on the file type.
Pro Flexible feature-set
Vim allows users to include many features found in IDEs and competing editors, but does not force them all on the user. This not only helps keep it lighter in weight than a lot of other options, but it also helps ensure that some unused features will not get in the way.
Pro Asynchronous I/O support
Since Vim 8, Vim can exchange characters with background processes asynchronously. This avoids the problem of the text editor getting stuck when a plugin that had to communicate with a server was running. Now plugins can send and receive data from external scripts without forcing Vim to freeze.
Pro Has been supported for a long time and will be supported for many years to come
Pro Donations and support to Vim.org helps children in Uganda through ICCF Holland
Pro By default in Linux
Pro Terminal with root access
Cloud9 gives full terminal access to home directory. In their hosted Linux Ubuntu environment it has sudo powers. No UNIX commands have been blocked - npm, ifconfig, chmod, chown, tar, etc work. All commands can be accessed and any package can be installed. However, certain advanced features are inaccessible (one cannot run Docker within the terminal).
And if the terminal is used when using Remote SSH feature it connects directly to the server and runs the commands on that server.
Pro Provides with own runtime environment
Cloud9 can connect to a dedicated VM to provide a powerful Ubuntu runtime environment in the cloud using Docker. Apps can be either run from the run panel where a selection of runners is provided or from a terminal.
Pro Can be hosted on own server
Since Cloud9 is an open source project with source code available on GitHub, it can be run as a self-hosted solution on own hardware and behind a firewall as long as it's being used on non-commercial projects.
Pro Git & Mercurial support
Git and hg commands can be run in the command-line, the same way as in a local terminal. There are also built-in add-on services for GitHub, BitBucket and GitLab.
Pro Capable editor
Cloud9 uses their own editor called ACE. Besides the basics, it covers most important advanced code editor features such as code folding, converting cases, auto-completion, code analysis and refactoring, regex search and offers easy access to relevant documentation.
It also gives access to the CLI, has support for Vim and Emacs keybindings, includes multiple cursors and zen coding mode that removes all distractions and allows focusing on code.
Pro Enables real-time online collaboration
An important feature of Cloud9 is the real-time collaboration ability. It allows pairing programs or perform code reviews really easily as well as simultaneously text chat.
Pro Runs any language
The runner has built-in functionality fo Apache, Node, Python, Ruby, Ruby on Rails, Go, CoffeeScript, Julia, Mocha and Shell script, but any other language can be used by creating a runner for it.
Pro SSH Workspace
Allows you to connect directly to your external server via SSH. Modifying files directly on your server using a cloud based editor allows you to have the portability of the a cloud based workspace with the control of your own server (including complete DNS control).
Breakpoints allow specifying a stopping points in the execution of the application. When these breakpoints are hit, the application will stop executing and give the ability to examine data such as local variables, run commands and control the execution flow of the application.
Pro Ability to clone multiple repos in one project
Cloud9 provides one free private workspace. However, I can host multiple projects there by cloning as many repositories into the root project directory, thanks to the full access terminal.
Pro Provides with a simple way to deploy apps
Pro Support for most databases
In addition to launching a server to run code, Cloud9 will also host a database to develop against. Support for MySQL, PostgreSQL, MongoDB and SQLite.
Pro Package manager
Similar to package managers for the desktop, Cloud9 also includes their own package manager, c9pm, which allows adding new software from a list of available utilities.
Apt-get can be used in the project's workspace terminal to install/update/upgrade software. Composer, Bower or any other utilities of choice can be installed to manage dependencies and packages.
Pro Offline editing
By installing and running a client application that syncs the local file system and cloud storage Cloud9 can be run locally. Great alternative for situations when the Internet connection is unreliable.
Pro Browser testing support
Cloud9 integrates with Sauce Labs a browser testing suite that allows previewing the app in any desktop or mobile browser.
Pro Great documentation
Cloud9 has extensive, well-organized documentation at docs.c9.io.
Pro Bitbucket integration
You can launch into C9 directly from the Bitbucket UI via a plugin available on Bitbucket. If you set up your Git repo for a project in Bitbucket and open it in C9 you can push to Git via the CLI from the start.
Pro Built-in image editor
Includes a very basic image preview and editing tool.
Pro Ease of use compared to e.g. WampServer
Con Difficult learning curve
You'll spend a lot of time learning all the commands and modes supported in Vim. You'll then spend more time tuning settings to your needs. Although once it's tuned to your needs, you can take your
.vimrc to any machine you need and have the same experience across all your computers.
Con Poor support for external tooling
Many plugins depend on optional Python and Lua features, which may or may not be included in whatever binaries are available for your system. And without platform-specific hacks, it is difficult for plugins to operate in the background or use external tooling.
Con Poor feature discoverability
Though basic features like syntax checking, autocompletion, and file management are all available out of the box or with minimal configuration, this is not obvious to new users, who might get intimidated or assume they need to install complex plugins just so they can have this functionality. Other features new users might expect to find embedded in Vim, such as debugging, instead follow a UNIX-style model where they are called as external programs, the output of which might then be parsed by Vim so it can display results. Users not familiar with this paradigm will likely fault Vim for lacking those features as well.
Con Doesn't play nice with the system cut/paste mechanisms
This can be worked around if you disable mouse for insert mode. You can then right-click your terminal and use paste like you would anywhere else in a terminal.
Con Works poorly out of the box with right-to-left
Con Once you're used to it, you won't like other editors
When your fingers have learned Vim's keyboard commands, you'll find yourself reaching for them even when using other text editors. You'll get frustrated every time you have to reach for the mouse or move your cursor letter by letter with the arrow keys. You'll notice every time a Vim feature would save you time and tedium, and you'll wish the editor you're actually using had it. You'll wish the editor was Vim. You'll wish everything was Vim. You'll wish this imperfect world we live in could somehow become just a little bit more graceful, a little bit more elegant, by adopting modal text editing as a common paradigm. You'll wish desperately that this world was that better one. But it isn't. It isn't. And it never will be.:wq
Con Slow when opening files with very long lines
A lot of very long lines can make Vim take up to a minute to open files, where a few other editors take only seconds to load the same file.
Con Foreign keyboards have a hard time on Vim out of the box
A lot of frequently-used keybinds are way harder to access on foreign keyboards because they use different layouts.
For example, Germans use the QWERTZ layout, while French use the AZERTY.
Con User must remember commands instead of point at them in a menu
Con Unintuitive mode switching
Con No smooth scrolling
Even with the GUI version, the lines jiggle line-by-line. If you are used to smooth scrolling, this is very annoying, especially when working with larger files.
Con Consume brain energy for editing that should be used for logic
Text editing in vim is awesome, but it requires thinking about combination of commands. In other editors, you don't have to think about how to delete this part of code. You just think about how to implement a feature, what is a good design for this code. Even after you get used to using vim, it still requires your brain for editing.
Con High effort to customize
Con You need a credit card to sign up
You need a credit card to sign up for Cloud9, which is problematic for users in countries where credit cards are not the norm.
They won't bill you (for the free account), but still require it. You can buy a VISA gift card and sign up with that.
For more than one private workspace, the starting price is $19/month.
Con Lacks a built-in Java builder and runner
While there is no built-in Java builder or runner currently, C9 has provided instructions on how to set them up. Instructions can be found here.
Con Cannot run "chroot"
This breaks many developer tools like Docker and Bazel. This is the result of the fact that the hosted environment runs within Docker which limits access to this capability in order to prevent breaking out of the container.
Con Lacks subdomain options
Building an app that needs subdomains is impossible.
