Yeah, half of my coworkers used to be on CLion (for Rust). TBH I couldn't get past the fact that it reminds me of Java IDEs with too many things going on. What's better compared to VSCode?
It's hard to start at anything specific :)
I haven't seen a single person who seriously used both and went back.
Search, VCS, keymapping, defaults, heuristics, refactoring wide of use, AI-based autocompletion - there's simply no real adversary.
Last time I was blasted when copying an old DB to a one in a new DB it correctly guessed the renamed columns based partly on type and size, partly on column names.
Also I love its suggestions so much that when learning a new language I always look at Jetbrains' respective autosuggestions - simply because it makes me a better programmer, faster.
