Smash Ace
Nevermind, ASC sucks at breaking the attachments on Brinstar's ledges, best you'd probably get would be like 17%~ on it with ASC->SDR.All in all, I can't imagine many situations where spindash would be fresh (because soooooo many of our best options involve side b and down b which stale together in all their forms), but its nice to know that. MK in the air would have no options for going through you, but obviously he could just land on the platform (unless its that one part of delfino) and you wont be invincible if you try to get him there.
Its a shame Sonic doesn't have any godly powerful move for breaking stuff on brinstar, we might actually be good there.
Edit: did a bit more testing with it, and ASC->SDR can only be slightly better than a fully charged fsmash for breaking the pillars on Brinstar
Also, I whole-heartedly agree with Cloud's opinion, that Sonic *does* look and feel much better/fluid in brawl's physics. That's for the most part why I don't play PM.
On a side-note, personally I feel Sonic's perfect the way he is in brawl, flaws in tact, thanks to his few but gaping flaws, he's not broken like another character we all know and despise
