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. 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 Full terminal 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.
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 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 Great documentation
Cloud9 has extensive, well-organized documentation at docs.c9.io.
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 Integrates with AWS
Prior to being part of the AWS Toolchain, AWS integrates deeply with CodeStar and AWS Lambda, allowing you to build serverless architechtures.
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 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.
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 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 Desktop application is available
Prior to the Cloud9 core source code being released, an Alpha version of a desktop version can be built from the source which is based from NW.js. Instructions can be found here.
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 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 Provides with a simple way to deploy apps
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 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 Browser testing support
Cloud9 integrates with Sauce Labs a browser testing suite that allows previewing the app in any desktop or mobile browser.
Pro Provides with a simple way to deploy apps
Pro Provides quick fixes
Eclipse with JSDT provides you with quick fixes every time a warning or error is raised by the IDE. This feature is particularly helpful at places in code where errors were caused by the programmer just being a little "lazy", such as missing out the
+ sign between two operands or a variable being out of scope.
Pro Smart Code completion
Just like all other IDEs, Eclipse offers you inline code completion (even with any external JS libraries added to the project).
Pro Free and cross-platform
Eclipse runs on Windows, Linux and Mac, and is totally free of cost.
Pro Code refactoring
Eclipse's refactoring features are quite similar to Webstorm's. It provides almost the same functionalities which include renaming, moving, and member extraction to make your code tidier
Pro Code auto-completion for brackets and parenthesis
This feature is particularly useful when you've added a lot of nesting in your code and you're unable to recall which opening bracket corresponds to which closing one.
Pro Large selection of plugins
Eclipse has a large and active community, which has resulted in a wide variety of plugins.
Pro Highly customizable
Thanks to the large variety of plugins and various configuration options available, Eclipse is very customizable.
Pro Seamless integration with web servers like Apache or Jetty
Eclipse lets you integrate web servers (like Apache or Jetty) into the IDE, which you could use for in-container testing or providing services.
Pro Good integration with git using eGit plugin
Pulling, pushing, staging, stashing, etc., are all available in Eclipse as IDE functionalities.
Con Lacks subdomain options
Building an app that needs subdomains is impossible.
Con Part of Amazon Web Services
While the c9.io site is still up and running, Cloud9 is exclusive for AWS Customers only, and you pay the AWS Compute pricing when you use Cloud9.
Con Free plan asks for credit card details
Free plan requires you to provide a credit card due to the nature of Cloud 9's "Free Workspaces" to be relatively abused. According to the developers, this is the only way to prevent such.
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 Does not accept New Registrants on c9.io Anymore
As being acquired by Amazon Web Services as part of AWS Cloud9, the c9.io service won't accept new sign ups.
Con Terminal will not work on Windows (Cloud9 SDK)
The terminal package does not work on the Cloud 9 SDK in Windows because it cannot find an appropriate unix shell. This might be a recurring bug undergoing fixes.
Con Uses a lot of memory
Eclipse hogs a lot of memory, although this can be controlled by the IDE start-up ini file.
Con Plugins can be unstable
Though there are plenty of plugins to choose from, they aren't always reliable. Some aren't maintained, bug fixes can be slow, and you may need to download plugins from multiple sources.
Con Support and problem solving is difficult to find
The Eclipse forums have more tumbleweed than users. Stack-overflow also has very little info.
