I tried it last year in a failed attempt to get of ps, which I to every few years.
I can’t name specifics, but ps is just more intuitive, more user friendly, faster, more stable, gives you more for formats… I don’t even think ps is all that. Even if we forget Adobe owns the pro space here, it’s just not viable to use gimp professionaly. I never understood why gimp doesn’t just copy all the user flows from photoshop when it’s clear that not only they work, but all users are familiar with them from other software.
