The Gerudo, without a doubt.
I don't know whether it's just my liking for Ganondorf that tends to influence me over decisions like these, but I love the Gerudo race as it stands. Their leader is freaking epic, no matter what game he's in, and speaks a lot for the race itself, with his command, his cunning, and his great, great elitism. They seem to be a very distant race, that needs to be explored a lot more in future games.
From what I could actually chose from, the Hylians. They've definitely got the best people, and the second most interesting storyline.
