Legion or Tali?
Legions an elite collective and such an advancement in tech it really isn't even fair to compare him to dime a dozen moronic quarians who couldn't even control their own fuckin slaves. On top of being worthless and extremely fragile without biohazard suits.

AI's are usually the best sci-fi factions, in that most sci-fi universes are badly written and their the only faction that actually does cool sci-fi shit instead of being boring assholes.
I romanced Tali and even I know that Legion is infinitely better.
