CLion uses the same base as IntelliJ, and a lot of the refactoring functionality it provides is shared with Resharper for C++. If you still want Visual Studio, I highly recommend checking out Resharper for C++.
As the ability to refactor quickly and easily is one of the most useful features an IDE can give you, and as one of the most important parts of any long-term software development is the refactoring, and as good refactoring tools are what JetBrains do best....you can see the appeal of this IDE. Plus, free.
