You know what? It's fine to ask people here what the differences are between the versions, but don't rely on anyone's post here to make your decision. Each of us is slanted to wards a certain version, each of us has experienced a certain version running well for us when it might not run as well for you. There are so many variables in the users and their PC's that we couldn't possibly give you a definitive answer.
I'm afraid it's "buyer beware" my friend, each version has it's pros and cons, but how they will work for you is a mystery that won't be revealed until after you've installed the last patch.
I wish you luck in your choice. Remember,...behind one of the versions is a hungry tiger!
