hopefully not photoshop - i dont like it
Hate to break this to you, but unless there's something very specific about Photoshop you don't like ("the price" is a popular answer) you're going to hate pretty much any application able to turn out reasonably professional work. PS is the standard, so most everything else can be categorized as "Photoshop, but with..."
e.g.
Painter: Photoshop, but with better brushes and tablet support (and horrible memory management).
GIMP: Photoshop, but with that "I had to learn to do something special to get it to run on my system" open source street cred.
Pixelmator: Photoshop, but with HUD style windows, a lower price point, and an immature code base with a few counterintuitive interface choices.
Not to suggest any of these aren't fine choices depending on your particular circumstances. Just that if you generally hate Photoshop, you really need to be considering farming out your graphics work to somebody who doesn't, because you'll be hard pressed to get out of its shadow.
