Ranked in these QuestionsQuestion Ranking
Pro Extensive list of packages
Atom has a built-in package manager and an extensive list of packages. Packages are written in CoffeeScript.
Pro Built-in package management
Atom was built from the ground up with the community in mind. Package management is therefore a first class feature.
Due to its modular design, almost any aspect of the editor can be changed. Even seemingly core packages, like those taking care of search and replace functionality, can be forked on GitHub, and changed and replaced in the editor.
The documentation for creating new plugins is also great, making it easier for developers to jump in and create plugins for Atom.
Atom can run on Mac, Windows, and Linux.
Pro Free and open source
Atom is free, open source, and written in C++, LESS, and CoffeeScript.
Pro Beginner friendly
One of the goals of Atom is to be a text editor for both experienced and beginner programmers. You can add keyboard shortcuts, change themes, install plugins, and change core settings by clicking through a GUI, or by manually editing config files the old-fashioned way. It has the added advantage of being built using the same engine that powers Google Chrome, so actions like opening and closing tabs feel familiar, even to new or non-programmers.
Pro Embedded Git control
Atom will highlight folders, files, and lines that have any uncommitted edits made. It also integrates really well with GitHub.
Pro Multi-line select and edit
Multiple cursors and column selection allow for versatile ways of editing.
ctrl + d will select the current word and each time the command is repeated, it adds the next occurrence of the word to the selection.
ctrl + click or
middle-mouse click will place another cursor in the place that's clicked. Cursors can then be controlled together. This also allows for selecting vertically.
Pro Command Palette support
The Command Palette permits fuzzy searching all available functions, settings, snippets, etc.
Pro Allows for instant file switching
By pressing Ctrl or Command + T and using fuzzy search, you can look for a file in your project.
Pro Command line integration out of the box
Installing Atom adds two command line commands -
apm. The first one runs the application itself while the second is the Atom Package Manager that's used to add and remove various components from the package listing. While these features can be set up with other editors as well, Atom takes care of them out of the box.
Pro HiDPI support
Atom has built-in HiDPI support with zero scaling issues.
You can theme and customize Atom to your liking.
Pro Vim plugin turns Atom into a modernized vim
Pro Modern feel and very customizable and extendable
Pro Best support for Arduino with Platformio
Arduino is the most important platform for developing embedded systems.
Pro Provides a consistent experience across OS X versions
MacPorts eschews Apple-supplied libraries and links sources against its own making sure that the experience is the same regardless of what OS X version is used.
Pro Generally very up to date
MacPorts generally gets new software soon after it's available. This way users will not have to worry if their software is up to date.
Pro Nice variants system
MacPorts has a variants system that allows customizing builds with author provided options.
Written in Tcl & C, it's generally significantly faster than the competition. Tcl is also quite readable and comparable to Ruby, so it's also friendly to newcomers.
Pro Has many more packages than its competitors
As of this writing, 20K packages. 3 to 5x more than other current package managers.
Pro MacPorts is a native application: C + TCL
No need to install Ruby, or any other programming language.
Pro Requires SUDO to install apps
No need to worry if some rogue app will change your binaries or configuration.
Pro Most of the available packages work
For example, trying to install Finch using Pkgsrc doesn't work, while installing it using MacPorts works perfectly. Finch isn't even on Homebrew's radar.
Con Very slow startup time
Atom is very slow to startup, which is a big disadvantage if you are accustomed to using it to make quick changes on your files.
Con High memory usage
Atom has a relatively high memory usage, especially when compared to some other text editors not based on Electron. For those who develop on the go, this also tends to mean shorter battery life.
Con Has difficulty with large text files
Tends to crash or hang with large >(10MB) text files, making it less useful as a general text editor.
Con Slows down exponentially with plugins
Extending it needs sacrificing responsiveness
Con No text UI
Con Doesn't handle RTL (right-to-left text) well
Text can't be highlighted and manipulated properly, cursor isn't displayed visually according to where it is logically (you have to type to find out), and similar issues.
Con Not known when a new window will open
It's not really clear why and when a new window is opened when you open a file out of the tree view.
Atom is not a native application. As such performance is subpar and the lag is especially noticeable on larger projects. It also opens a surprising amount of sub-processes and leaks a considerable amount of memory.
Con Missing additional touches
As Atom is still relatively new, it's missing nice little touches that other text editors have implemented over the years. From simple ease-of-use items like middle-mouse button multi-cursor select, to the ways pasted information from a spreadsheet is interpreted in multi-select situations.
Con Crash and data loss
I lost unsaved changes 2 times when the app crashes.
A bugreport about that was closed automatically after some time, nobody cares.
Con Doesn't recognize some keyboards
Con Bad at limiting dependencies
MacPorts has a habit of pulling very specific versions of dependencies for each package. It downloads different version of already existing dependencies even in cases where the existing dependency version would have worked seamlessly.
Con Downloads unneeded libraries duplicating functionality already provided by Apple's libraries
As MacPorts eschews Apple-supplied libraries and links sources against its own a large duplication of functionality across MacPorts and Apple libraries can be found.
