+1 for Krita. It is developed in tight cooperation with many artists who use it daily. It is similar to Blender in that regard. Just read some of their artist interviews (https://krita.org/en/features/artist-interviews/ https://krita.org/en/features/artist-interviews/). Also, being part of KDE, they have a very strong UI/UX team that does lots of a/b testing and other usability testing, which I sometimes feel the Gtk devs are lacking in (however, I don't follow Gtk development too closely so I might be wrong here)
