CLion is IMO by far the best option out there, short of going the editor-as-ide road (vim emacs etc).
QtCreator is good, but only better feature wise for qt/qmake projects.
VSCode is difficult to setup, the billions of plug-ins all lack something. I remember struggling to get remote debugging to work properly, I think because I couldn’t override the default gdb flags to use local symbols (downloading 10gb of debug symbols every run, thanks but no thanks). Amongst other things I can’t recall. It’s probably a decent IDE for JS or hobby projects but I cannot recommend this for a professional environment.
I’m not gonna bother discussing VS.
What else is still around and actively developed? Codeblocks? Netbeans?
… Or as shown by the west for the past 150+ years
