It's not that I think the Classic team is necessarily better than Core (although I do highly respect Gavin and Jeff Garzik), but we're frustrated.
That is the really nice thing about Bitcoin - being algorithmic it doesn't care that you are frustrated (and you should perhaps go out and find someone to help relieve that problem).

By "frustrated", I don't mean "emotionally" but rather dissatisfaction/disagreement which has led to the alternative implementations.
