To me Adobe has very bad UI, I did try to use it, and first time was awful. Freehand was a lot more intuitive, but when Macromedia was bought, was killed.
I get, that a lot of people did learn to use Adobe UI, and of course they want the same because they’re used to, but doesn’t make it better.
Affinity is more friendlier that PS to me.
I’m not saying that GIMP UI is perfect or good, but right now, to my casual use case, is not bad. Obviously can be better, and get some ideas from other UIs.
