Yes, that does give him the upper hand in so many matchups.DDD's CG's/infiniates and bair alone make him top tier.
But it's the small, fast characters that have the potential to take him down. I've played against some DDD's with Sheik, ZSS, Kirby, G&W, Metaknight, and especially Diddy Kong. If you watch Gano play against some of Japan's top DDD's, you can see that Diddy might have a pretty clear advantage. I can see why DDD is top tier because of his grabs, but it may blind some to the fact that he has some terrible matchups in the small characters.
