If you're in a very, super high end raiding guild and looks don't matter to you at all, not even a little bit, then goblin is probably the best option. Berserking is as you assumed correctly, the 2nd best choice.
Orc is a legitimate contender if you want to consider an enhancement OS.
To me, Tauren or Orc for looks.
