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.
Switching is so worth the effort. As someone who used Photoshop since it’s initial version, until last year, it took me a while to get used to GIMP. But now I must admit that I love it. Keep with it and you will love it as well.
