Tried use GIMP a few times, but the standards feels way too different from Photoshop.
Like basically everything.
I’m not a designer, but I use such tools once in a while to make some images, and GIMP is nearly impossible to use for me.
Currently I’m sticking with Photopea on browser.
Gimp is weird. However, if it doesn’t click with you there’s other options (depending on what kind of workflow you’re trying to do). Personally, I prefer Krita, but inkscape is also an option.
Inkscape is even weirder if you’re coming from PS/GIMP/anything else that’s primarily a raster image editor. I do like Inkscape but it’s not immediately obvious how you even draw anything; I had to look it up.
