Atom is great for developers looking for a completely hackable experience. There is a ton of plugins available to you, and you can really build an editor that matches your own personal taste. The performance is also pretty neat and does not impact your CPU as much as the competition.
CLion is best suited for day to day IDE for C and c++ programming projects. It integrates inbuilt support for GNU Compiler Collection (gcc) and works like a breeze on linux and *nix based platforms. While using this CLion IDE for different versions of projects, we faced a little difficulty to compare the differences of two versions of same file. This could be taken care of in next versions.
Atom is highly customizable and allows for various themes and extensions that can make your code easier to read.
Atom has many code hinting features that allow users to write faster and integrate with services likeLINT that can clean up your code once your done to meet your internal teams style choices.
It's very fast and manages projects well - Accessing other files within a related folder(s) is very easy and intuitive.
Well Atom is open source so the re-new is a no brainer. The only way I would stop using Atom is if the developers somehow made it not function well. Or, if the project got forked to a commercial version or something. Or, there could be the case that development stops or that it was not updated on this or that platform
I give Atom a 9 because it is one of the most modern text editors built with JavaScript intentionally to allow the editor to be changed and modified with custom functionality that a team may need. I think I would otherwise give atom an 8 due to support, but it gets a 9/10 because of the extensibility/plugin capability.
CLion does everything I ask it to do. For me, Unreal Engine 4 compatibility was essential and Epic Game and JetBrains delivered a solid alternative to spending a huge amount of money on the "standard" IDE for game development on Windows. The user interface is sharp and modern without all of the silly frills many software suites now employ. It integrates well with source control systems we use and also works well, as expected, with other JetBrains development tools and assistants.
Atom has an active forum and a Slack group where you can ask technical questions. Occasionally, the authors will pop in to answer a few questions here and there, but most of the time, its other helpful users who will assist you. Though they aren't the most knowledgeable, they are at least timely.
As for plugin support, that differs with each plugin, but as I mentioned before, many plugins are no longer maintained.
I am giving it a 9 out of 10 because I did not even need official support from the CLion team but rather, every time I came across a problem, I have been able to solve it within the community itself. This is so precious that you don't even need the help of the program's development/support team. There's a huge community of users that backs you up.
They are both pretty good; however, Sublime is free to use but on a trial basis. Atom is free open source. Sublime doesn't have the Github integration or a project file browser. Sublime does have a workspace view option but haven't really used it as much as Atom.
The tool we use when we need quick fixes. Allows fast, reliable scripting to fix urgent problems in our applications.
When applications grow from 5-10 files to 100's, they need to be migrated to a heavier-duty IDE. This can be cumbersome and quite annoying, but is necessary to maintain code integrity on such a large scale (since it cannot be done with the limited default toolset of Atom).
