I completely agree.
Every few years I give GIMP a shot, and every time I give up because it's completely inscrutable. Adobe is evil, and Pixelmator lacks features, but at least you can figure out how to use them in short order.
Check out Krita, it's a much easier lift for someone used to photoshop ime.
At least, if you're doing digital art. Not as full featured for editing of photo's.
Every time I give Photoshop a chance I give completely up, the thing doesn't even start on neither Fedora or Ubuntu and I have no interest in configuring Wine for this. GIMP is the least painful way to get the job done. I have been using it for over 20 years, and it has been a pain-free experience. That GIMP is bad is just as wrong as the people who say Java is bad.
But you know what's even worse, people that use Illustrator to create SVG's for the web. Inkscape creates proper readable SVG's at 5KB, compared to 50MB SVG's I get from Illustrator experts.
