Smash Champion
See, I was thinking Falcon does the Up b over Marth and Marth is less capable of punishing that than Peach. Marth at best gets an f - smash which hits him to the other side of the stage, a lot of times though it hits him far enough that Falcon can still recover to the ledge with a sweet spot double jump. Marth's throws don't really combo to any thing, no aerials will hit hard enough to get him away. Where as Peach's dash attack > nair , up throw > nair, d smash, or f throw can keep Falcon off the ledge on the side of the stage he is closer to.Not only that, but marth's gimping power on falcon and ability to cover all options with his sword is ridiculous. A lot of times, falcon can up-b over peach and land on the stage, then she can't hit him off again (or hit him in general sometimes), whereas marth's tipper is pretty damn strong and knocks him off the stage at mid-percents guaranteed. Or if he wants, he can just combo falcon, then knock him off the stage.
I still don't buy marth's gimping power on Falcon. Any throw off of the stage it's very easy for Falcon to double jump to the ledge with a sweet spot and not get hit by d tilt or f smash. Marth could always run off with fair or something but if Falcon jump back early with a up air or nair it can reverse the whole situation.
Falcon has guaranteed KO off of grabs, with up throw > up air > knee or d throw > knee. His forward b cuts through most of marths aerials and covers his dash dance at close range as well. Even if marth blocks he can't punish very strongly. Marth relies on tech chases and spacing to shut him down, meaning, every hit with Marth is a new hit. Not a lot combos. With Falcon, everything combos and all of those combos lead to knee. His ledge guarding against Marth is very good too. B air cuts through marths fair and forward b, up tilt catches jumps onto the stage. If Falcon ledge hogs Marth and forces him to land on the stage its a free knee, usually he can get a reverse knee to which guarantees the kill.
Falcon can spam short hop attacks against marth with low risk high reward. The attacks will jump over grabs and d tilts. Most aerials won't actually combo into anything, they will hit Falcon away but he'll still have the chance to roll against any follow up. Marth has to use mind games to follow up his attacks. I've said this before but this is why Falcon wins, Falcon doesn't have to mind game anything. One hit leads to a guaranteed combo and most of the time that combo will KO.
Even though I'm old school I don't rate marth that high because I think he has been around long enough that people have figured out how to play against him and people's tech skill has developed enough consistency that Marth's strong punish game isn't as good as it used to be. Marth is one of the least technically demanding characters, so early on in the game when people made more mistakes and couldn't play as fast with tech characters like Fox, Falco, and Peach, you'd see Marth win a lot more. People now are strong enough that they don't miss L cancels and get shield grabbed > death combo. They've seen the gimps enough time that they don't panic when thrown off the stage, they keep their nerves calm and recover with a well spaced double jump.
As for Peach, when people start beating Armada I'll consider ranking her lower. For me, one person winning consistently with a character is enough to rank them at the top, even if the character is less common. When Ken was dominating people didn't think Marth was the best, they still thought he was high but it's just that Ken was so good. People say the same thing about Mango and Hbox with Jiggs. I don't buy that, I think that because the character is less common it makes them a better character because the overall knowledge within the community on how to fight that character is lower.
