It doesn't have to mirror Photoshop, but the UX has to be good. With Gimp, it's not. People can claim all they want that Gimp is fine (after getting used to using it), but there's a clear voice in the public that Gimp's UX is terrible.

I used to hear people complaining more about the UI before the single window mode became available. Nowadays I hear few complaints about the UI. That isn't to say it's perfect, but I get the impression people have other concerns now.

I definitely agree, the single window mode is way better.

I’ve used multiple image editors for 25 years and the UI is fine, meaning good enough.
