Having a good debugger integrated with my code editor is basically the reason I use an IDE instead of vim. Stuff like Vimspector exist but are way more work to use vs. a GUI equivalent.
I have a (maybe overbroad) critique of GUI software which is that it mostly brought us pixel-level graphics at the cost of extremely restrictive UX. Or said a different way, GUI apps look better but they're usually harder to get work done in.
Part of that is toolkits, part of that is you're using a mouse which is like driving a space ship with a single finger, part of it is the expanding user base of computing (to people who don't necessarily want to learn say, regular expressions). But like, I script GDB. If your IDE debugger won't easily let me do that (or it will but it's a painfully convoluted UX), it doesn't really matter to me that it (subjectively) looks nicer.
The sole exception in my opinion is remote debugging (it’s not too bad, but JetBrains really bootstraps this part very well).
