This is an very interesting matchup imo, fun to play. I have some experience against Peaches so here are some things I have to say:
We can out maneuver Peach but it's tricky. We're faster than her both grounded (by a huge margin) and in the air, though her float give's her good enough aerial control that she can a lot of times make us miss with our aerials while throwing out one of her own to punish. Peach definitely beats us if we don't consider movement and baiting, so you're going to have to use your speed, especially ground speed, to beat her superior ground game, but again it's very doable, and you only need to land one move on the ground to put Peach in a bad position.
IMO, we don't get juggled badly at all in this matchup which is a huge point in our favor since that can be really bad against some characters. The battle in the neutral position is focusing much more on the horizontal spacing game, and who can juke the other into making a mistake. What I've noticed is that Peach will have difficulty dealing with our grounded spacing (dsmash, dtilt, jabs), especially dsmash, and will then resort to trying to float at head level to avoid these spacing moves. If you see Peach looking to start a float, I found you can usually run and shfair before they can get an aerial out to cover themselves.
The horizontal spacing game is pretty fun. Peach's fair outranges our bair slightly I think, that thing is massive, but we outspeed it so we can take advantage of that. It's also easy to see coming and shield, but do not try to punish it OOS. Peach fair autocancel to jab outspeeds even our jab OOS, unless you PS it of course. I usually try to avoid this situation all together instead, by getting Peach's face and staying in the air more.
Camp game: Peach's turnips are.. okay. With ground speed as fast as ours, you can punish Peach for pulling turnips fairly easily with either dash attack or grab, which are both excellent punishes in this matchup, so this makes the turnips a lot easier to deal with. If you let the Peach pick them all the time you will have a really hard time because of the many ways they can use them, to create grounded combos with glidetoss, for space control thrown vertically, or holding onto them in float to combo with aerials. Since they fly fairly slowly in the air, if the Peach is being predictable with how they are throwing them, we can simply jab them out of the air pretty easily to catch them. Peach can hit you right after you try to catch them though if they catch on, so don't get frame trapped.
Our suitpieces are very good if you can manage them well. They serve to get Peach off the stage, which is great because while gimping Peach is pretty tricky since we can't do much to punish their up b (besides Nick's dazzle apparently lol), Peach has a very hard time getting off the edge back onto the stage if you play your cards right.
The pieces aren't as effective in an actual juggle situation like they normally are only because Peach's dair is very good at canceling them out. You can still bait the dair with the piece and aerial to punish, however, and if she airdodges well you have a ******** amount of punish time on your hands against a slow falling character. Seriously, if you can learn to outspace the dair with our uair, Peach should never come down from a juggle. However this is easier said than done, and Peach can mix it up between floated dairs and fast falled to make it trickier for us.
Aerial peach vs us on the ground is interesting, definitely in Peach's favor. Peach will generally either fair as a transition to her ground game, or pressure our shield with dairs and nair to the ground, in my experience. If peach is dairing your shield, first of all angle up cause it pokes hard. Depending on how Peach maneuver's the float is how you can attempt to punish/escape the situation; if she dairs and stays on top or moves back in front of you, uair is a good punish. If she moves behind your shield she will probably try to come for another pass or bair/nair down to the ground. None of this is easily punishable, so i would probably just froll away and reset. The lesson to be learned here is do not attempt to shield camp this matchup at all; instead of allowing her to dair your shield, fair her to begin with before she can put you in a bad position.
I'll write more if I think of more, but I think that matchup knowledge helps ZS loads more than it does Peach, and while this is a weird one I think it's 55-45, almost 60-40 but not quite
. But yep 60:40 Fox.
