GIMP and PS are extremely similar. Your skill level won't jump up by much if you switch to PS. However, there are many more tutorials available to a PS user but most PS tuts are applicable to GIMP as well.

I never knew that!  

Shocker. I like the PS a lot better then GIMP. It can let you do a lot more to an images then GIMP?

It let's you do more things quicker. But most effects done in PS can also be done in GIMP.
