Photoshop is not a lot easier than Gimp, it's a more advanced. Professionals use PS and Gimp is good for learning. I never used Gimp before but I've heard from people who use it frequently that it can be better than PS at times. I don't really believe that, but like Staxx said, it's preference. If you don't want to learn the complications of PS, stick with Gimp. However, it is advised that you move away from Gimp to PS once you become a Novice. There's a limited amount of things you can do on Gimp and majority of GFX artists use PS for it's versatility.
