It's hard to choose a race to dislike over all, because just like in the real world each has its fair share of jerks and friendly folk. But, if I have to pick one I guess I'll go with Imperials. Mainly because I've never been interested in playing as one.
As for weapon styles, they all have their own uses as well. Though, in truth, I use blunt weapons the least. Even so, there is just something satisfying about feeling the force of your mace cracking a bandit's skull to pieces.
