Basically every complaint about GIMP is also valid for photoshop. People claiming PS is "intuitive" or "easy to use" literally just means they already know the keybindings/icons/quirks of photoshop specifically. It's okay! I have the exact same experience the other way around when I have to use photoshop
This isn't true. There have been plenty of other applications (Corel, Paint Shop Pro, Fireworks, Krita etc) with their own workflows and keybindings that weren't confusing for users.
GIMP's UX is just bad. I loathe photoshop and desperately want to like GIMP, but each time I make the attempt the friction is too much and the workflows nonsensical. I used it a few weeks ago to place two images side by side in a larger canvas. It took half an hour in this mental little app to figure out how. I haven't have any issues with Inkscape and even Darktable ended up making sense. This is squarely a Gimp thing.
