CLion is suitable for any software development purpose I can think of, and probably many more than I have no envisioned. It joins offerings from Intel, Microsoft and the like providing a quality IDE that produces quality code. It checks all of the boxes a developer wants it to check. The only place it's probably not your best tool is if you are heavily invested in another IDE. In that case, I'd always recommend sticking to organizational standards for production work and explore competitive alternatives in the lab.
JetBrains, the company that created and maintains CLion, is located primarily in Russia. While that doesn't concern me it does create worries for some people.
No real cons. The product is great and the support is equally excellent.
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.
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.
Most IDEs are huge both in disk and memory which causes it to run slow, where CLion is much smaller and faster. That's what I loved about CLion, compared to its rivals. Not to mention its extensive abilities and functions in the debugging process, thanks to which, we were able to fasten our software development process.
