Hmmm I try to mix up my approach. My main approaches areAll of the scrub Peaches seem to think that float dair is a good approach, so they'll literally floaty across the stage at you while dairing. It's pretty lol-worthy.
Dair is a good move, but as I said, it should be used sparingly. Dair makes the Zelda MU extremely easy and I still have nightmares from facing your Peach on 3DS. Peach's Brawl aerials were great and I'd trade SSB4's aerials for Brawl's in a heartbeat.
Turnip to aerial.
Float Dair
Float Nair then drop float and go backwards right away
Float bair then drop float and go backwards right away
Run up then QFR and wait for them to do something
Float then I drop the float and grab
