Me too. I guess a majority of people don't have the patience to work around counterintuitive things nor do they want to take measures to avoid bugs. On the other hand, Blender and Krita seem to give UX a higher priority, so they're more likely to catch on.

I dislike using Gimp. Always have.

There is just something about it that does not click with me. Just selecting a foreground object even when the background was almost white never worked for me. Just so fiddly.

I can get stuff done with it.

Try PhotoGimp plugin, it solves some annoyances for me by introducing the shortcuts I used to, and a slightly more familiar interface. The rest, I just got used to, and actually now I like Gimp more than Photoshop (which I don’t like too much, even though I know it for two decades now).
