Yeah GIMP can be a PITA but I spent a lot of time in Photoshop back in the day so I have different ideas than they do about where things should be. Supposedly there is a Photoshop skin for it though. FWIW I was working with some guys at a University who are looking into replacement programs since Adobe is trying to screw them over with their new subscription model. I hear Paint.NET (Not MS Paint) works pretty well on a PC. It has some limitations (won't do RAWs) but its free and easier to use than GIMP. If its a Mac Affinity Photo has been doing well and I hear they have a PC version out not. Not free but cheaper than Photoshop
