It’s weird that you call Visual Studio snappier/faster than CLion. From my experience VS 2019 was extremely laggy even on small-size projects. I’ve heard from some gamedev veterans that VC 6 was the last “usable” version and performance/usability/responsiveness went downhill after that. (Here’s a famous rant by Casey Muratori who later compares the load times of VC 2019 and VC 6: https://youtu.be/GC-0tCy4P1U)

To admit, it has one of the best debuggers though. But CLion seems to have catched up in that department, and seems to have way better CMake integration than VS does. CLion still needs more work on performance (as well as support for other build systems), but it’s still the editor that I’m optimistic about.

I write C# code on a medium-large solution (ASP.net, 60 or so projects, ~1M LOC) and to be honest I don't know why everyone thinks that VS2019 is so great.

VS2019 frequently freezes for multiple seconds. When project files change (e.g. because you check out a different branch) VS often fails to load the modified projects and I need to restart the IDE.

Then there's the fact that the refactoring tools in VS2019, despite improving significantly since older versions, are still way behind ReSharper or IntelliJ.

I also generally dislike the UI I'm VS2019. The Git integration works, but it's cumbersome to use. You can't easily have multiple run configurations. The error/warning list pops up seemingly at random.

I use Rider now. It's not perfect, but I am just much more productive in that environment.

After trying both, I vastly prefer the workflow that CLion offers. Both are slow, heavy programs though.
