I have tried GIMP. It has a frustratingly senseless UI, and for some reason all of my pictures made with it have a really creepy vibe. I for one don't subscribe to the notion that great art comes from suffering, and for that reason I give the GIMP two great big thumbs down. Why can't the tools be in the same window? Why? Would that be the give away that it was reverse engineered from Photoshop and should be considered pirated software with an ugly weasel head?
