I have both of them, but so far, White 2 is my main game. I'm not very far in either game, though; I'm in Castelia City in White 2, and in Black 2, I still need to pick my starter (actually, I can't remember whether I started and saved any sort of a file or not, though I did download a wifi event onto it). I would love to have more time to make progress on both games, but so far, it hasn't happened.
