I'm not sure. The teams seem rather well-balanced to me. But I think thematically it would be better for the 'villains' to win (even though they aren't actually evil), as it implies that our heroes still have a lot of work to do, which in my opinion is just a more interesting position to be in.

It's less of a balance issue, and more about team chemistry. Most of team All-Star hate/dislike each other. I don't see them working well together at all. (It'll be a hilarious defeat, though)
