Death Knight races

So meet a noob that had gotten to max level and only had their one character, a pally, and was asking me a bit about DK's and I got mentioning what I think would be the best races to fit with them, and kinda wanna know what everyone else would thing if you take into account the different racials, Personally I have to say the Draenei thanks to the Gift of the Naaru and Heroic Presence ones, but what does everyone else say?
