I personally prefer Krita to Gimp, otherwise my real issues with Linux being:
Lack of pro audio support. Sure, a lot of open source plugins are available on Linux, but only 1 usable DAW (Ardour), and even that has it’s own “issues” (de facto paid, if you don’t want to wrestle with exact compiler and make versions the devs won’t tell you).
X11 is kind of dated, while Wayland is still not up to the task.
GNOME devs. After all the sabotage, probably done in order to force people to use GTK and their UX design sensibilities, they should be banned from any Wayland protocol discussion.
Elitist users. They’ll scream at you online for using a normal text editor instead of VIM, they want you to write little automated scripts for GDB instead of using something with a normal GUI, etc.

Bitwig has a Linux version. It’s proprietary and paid, but it’s very nice to use and comes with a ton of devices.
So does Reaper.
