@Tyger I say they are about equal! Though lately I've been enjoying Adventure Time a little more (probably because we're between seasons in MLP and I've seen every episode)
I watched the entire 1st Season of Adventure Time! yesterday and loved it!
@Colon: I have to admit that I am not that much a fan of cartoons and mlp is the only one I've really watched. That makes it more amazing in my eyes, that even guys who don't like cartoons that much can love friendship is magic
