Nothing is intuitive in that software.

UI/UX is a very very difficult job. I've only ever known a few UI/UX artists that were any good, and OMFG, are they expensive.

You can't just drop everything and focus on something where you don't have domain experts. Not to presume too much about you, but that would be like saying you need to drop everything you're doing and focus on brain surgery next year. UI/UX is art. It's a very specific type of art that, unfortunately, doesn't come easy for people. There are companies for hire that work professionally on UX/UI, but they're not cheap either. Anyone can spot bad UX, but knowing how to fix it in a way that works for everyone, that's nearly a unicorn.

I've been using gimp since it was released for daily driver projects.

I've been using Photoshop for about a decade when required for gigs.

I can get around either app pretty decently at this point.

If you drop any new user into either, they'll be absolutely lost.

If you drop a seasoned Photoshop user into GIMP, they'll not only be lost but be unable to use their vast array of plugins and macros and aren't quite (but non-technically are) impossible for the average user to work on.

We can't make Gimp Photoshop-like. We can make strides to improve Gimp, but it's beyond reach for the current team. Maybe we can start a crowdfund to get a UX company to take a stab at it, but even at that we'd need buy in from the developers and it would likely be an incredibly large rework, not unlike the current one that took quite a long time.
