I've used GIMP many times. Every time I do, I fight with it for hours, try looking up tutorials for how to do things only to find out that everything is different in the tutorial compared to what is happening in my version of the program, and then I rage quit and use something else.
Sorry but I do not find GIMP usable. Not that I have any interest in the ai clone either. I've heard good things about Krita, so next time I need to edit something I'll be spending some hours learning how to use that.
