I think we see more "dittos" in Brawl then Melee is because of youtube.com. I may be mistaken, but I don't remember people feverishly placing their melee videos like they do with Brawl.
I would agree that it's to soon to assume that we have seen everything Brawl has to offer, however, Melee will probably end up with more ATs. It's not something I fault Brawl for though. While Brawl's system may not offer as much AT's as Melee, Brawl does successfully level the playing field between casual and hardcore to create a larger body of competition. Whether this is a good or bad thing, is totally up to you.
A lot better thread then you're last one BTW.
