D3 is really limited as a character. He does great versus the mid to low tiers but when you get into the higher tiers he just doesn't do that great matchup wise. He loses to Pika, MK, ICs, Falco, ZSS, Oli and has signifigant problems with Pit, Diddy and Fox. Not sure if those last 3 are really in their favor but either way its more problems than Pit has.
You underrate Pit's ability to recover. Sure he has one "Woi" but getting hit out of it is extremely uncommon. He has more mixups to recover than most characters. Kirby is mediocre. Any character that can reliably get around Bair probably beats or at least goes even with Kirby. G&W is ok but I think he has a lot of problems with approaching a lot of characters without getting subsequently punished.I don't even agree with G&W and Kirby, much less D3!
What makes you think Pit is better than those? As far as I know these characters have it easier than Pit in a couple of more important aspects of the game besides 'ledge options', like punishment, follow-ups, recovery (there's practically no possibility of a Kirby/G&W/DDD gimp, but Pit only has 1 WoI), even viable killing options (Kirby's main spacer is also one of his main killers, and it's definitely a great spacer... Bair).
I don't see where you're going with this, man. Give me something to digest, I can't just change my mind if you scratch characters off like that.
