I work 99% in a terminal and fire up a JetBrains IDE when I need to do deep debugging. It’s so rare for me though that it’s worth more for me to get good at the terminal stuff. I’m sure this depends heavily on the type of work being done, game dev for example really needs a good debugger. That being said, gdb and others have perfectly fine text mode interfaces, albeit with a steeper learning curve.

As always, the “best” tool is the one your most familiar with that gets the job done. Text vs GUI doesn’t really matter at the middle of the bell curve.
