It doesn't really matter but the various passive resistances are obviously good and the orc berserking is amazing even if it's only once per day.
The khajiit though seem to get the short end of the stick, aside from their natural +30 swagger.
I would have to disagree, where as yea the x2 attack of bezerker is nice... It seems to fade when you get stronger. I would rather not become too power full. I'm already powerful as I am no boosted weapons or anything.
Yet, just the night eye alone is extremely useful threw out the entire game. Being that we no longer have night eye enchantments. I feel the kajiit got the best traits.
But all in all it's merely opinion
