Krita is pretty good. I find the UX reasonable and G'MIC¹ is a joy to use in there.

I enjoy using GIMP. Most of my (not very advanced) needs are met quite well. Looking forward to try out the more recent versions too.

		I don't think some stuff is reasonable, but for most stuff, I find it hard to use. And I don't come from Photoshop, so it's not like a problem of being used to another program or something
