It's a great fit if you’re looking for a user-friendly C++ IDE; comfortable with using Vim; looking for a fast, intuitive UI; or teaching your students C/C++. It wouldn’t be a good fit if you’re more comfortable with command-line based IDEs or planning to code in multiple languages, as it only supports C and C++.
I would recommend Vim in any scenario where text files have to be viewed, created, or edited on GNU/Linux computers. Regardless if you need to quickly change a few things in a configuration file, or you need to write up a full document, Vim is great. I wouldn't use Vim to view, edit, or create anything that requires "rich-text". In other words, if you need to format the text (bolding, font colours, word-art, etc), then Vim isn't the tool to use.
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 don't consider the steep learning curve to be a hinderance on the overall usability. I would rate this a ten, but to be honest a lot of people do get hung up at the beginning and just abandon it. However, for people who have made the moderate effort to get over the hump, nothing can be more usable.
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.
There is no commercial support for Vim. Thus, it will not get a mark beyond 5. However, community support is very good. You can easily find solutions for most of the problems in the community.
Vim's keybindings are a lot more complex than Notepad++. With that, comes a whole bunch of capability that Notepad++ just can't match. Emacs is comparable, in terms of capabilities--because Vim is built into so many unix systems, I chose to learn it instead of Emacs. Knowing both probably isn't a bad idea, but there's enough to learn in either camp to keep you busy
