You can go to the guides section and look at the post that has all the spells and abilities - and compare them. Not sure that will help, though.
I'll tell you this, SoE worked overtime to 'balance' the classes and game - so I doubt there is much in the way of a meaningful difference.
I wouldn't breeze over the good or evil thing. We started in FP - we are evil gnomes after all - but we couldn't stand it. FP's version of evil is "make everything the color of mud" and have everyone "talk down at you like a low-level PizzaHut manager yelling at some 14 year old who just dropped the cheese for the 23d time" - it's sort of a dreary, low-rent evil - a really depressing evil - an uninspired "you're back in Junior High School" sort of evil - yeah... that's it - FP is my junior high schoool - brrrrrr. Too evil. So we deciced to become EvilGnomes but ones who live w/ the goody goodies. The "otherhand" is that some npcs in Q are so syrupy sweet you wanna hit em. It drives us nuts, too. Oh for a neutral city...
