I haven't read recent posts yet, but I'm just going to throw this out here right now:

CRAP I copy/pasted the link to the Kirby boards before posting the quote I meant to use. *goes to get it*
ok, here it is:
This is coming from a guy who's beaten Chudat..just saying.
Also, thanks to the tournament I went to this weekend, I'd just like to point out more support for Lucario/Snake having an advantage over Kirby, since those are what I lost to. I truly believe I outplayed BOTH of the opponents that beat me, and they won because both Lucario and Snake are ridiculously good at winning, despite being outplayed (at least by Kirby)
I beat Lucario first game on PS1, he counterpicked Yoshi's Island. I should have won the set here and advanced, but I didn't. What happened was, he was on his last stock at 110%. I was on my second stock at a high percent. I was thinking "Alright, Lucario is stupidly strong right now, but I just need to land one KO move and I've got this." It did not work. He knocked me out somehow, and then I spent my next stock trying to KO him. I got punished with superstrong aura spheres/fsmashes and aerials for trying. The only reliable move I could land on him was Bair, and it soon became too stale to KO, plus his great DI saved him. He ended up winning the match with like 130-140 damage, and then beating me on my Brinstar counterpick due to bad play on my part.
Something similar happened with Snake...first match, I DESTROYED him first stock. His first stock ended with an epic finished (after I read/comboed him to high %, he pulled a grenade and picked it up, I upthrew him, which sent him flying, and the grenade exploded and killed him)
The thing is, despite me outplaying him in this entire match, he almost won the first game because Snake lives so long and kills so easily. Anyway, he counterpicked Battlefield, and won because I suck on Battlefield, especially against Snake. I banned Halberd, I'll make sure to ban Battlefield instead next time, because I don't suck so much there. He banned Rainbow Cruise, I took him to Jungle Japes because Brinstar + Snake = meh. Jungle Japes was pretty lame though because it was SUPER dark and I could barely see Snake OR his explosives, especially when combined with the glare from the lights. So I don't really know what to pick against Snakes anymore.
TL;DR version:
Lucario is at least 55-45 over Kirby because he can camp on his last stock and kill you really easily. You can gimp Lucario, but your chances of gimping him on his last stock are really low, considering he will barely let you touch him.
Snake is at least 60-40 over Kirby because he has essentially 4 stocks in a 3 stock match.
