I use Photoshop and altough i never used GIMP i have to say that Photoshop is better. Photoshop= More Profesional Gimp: Just good for introduceing you to graphics
I have used both and its easy to say that photoshop is far better. The resources for photoshop are so much better and there are so much more than GIMP has to offer. Also i believe photoshop is more userfriendly. But maybe im just saying that since ive had photoshop for a while.
