peach has better edgeguards falco has trouble edgeguarding her.
he gets gimped easily if he goes off stage. She can float at a perfect height to avoid lasers. dsmash ruins him. chain grab on FD.
that being said its not all that bad. when she's floating at the perfect hieght to avoid lasers, thats all she can do, she's not a threat at that height unless she comes down with a fair or something, but when she is doing the sweetspot float, its not a big deal to falco. Also, this is only really effective on FD. On platform stages, falco can use the platforms to camp her well and vary his laser height to hit her out of the normally unhittable float.
Sheild pressure isnt that hard, she can nair oos and b-up but for the most part if you're doing it right you're ok. also, crossing up throguh her sheild and pressuring the back is really good.
at mid percents falco and do full hop dairs to uptilts rinse repeat until she either techs or eats a dmash or fsmash. At low percents, forget te shine (unless they sheild) and just go dair happy for easy damage.
imo, the key to recovering vs peach is to go below the stage, unless u can sweetspot a B-over but even then she's likely to float out and hit you. If you go low, you can tech literally anything se tries to hit you with extremely easily. all she can do is edgehog to defend in which case you mix up your recovery.
i'd say even but it may be 5 points in either direction, its a really close matchup imo.
