The many flavors of Princess, Daisy and Peach Differences.

Well a more definitive difference has finally been spotted.

Daisy has Peach's Vegtable Knockback values from Brawl and 4.

At least puts her on Par with Richter who's difference may be a glitch

Daisy's Turnip knockback is the same as Smash 4 Peach's. So it was probably just an oversight they decided to keep in.

Beefy Smash Doods explore the differences and what they mean for gameplay.

Namely, Peach's Stitchface Turnips are better Ko options and her regular ones are better at off stage sniping.
Daisy on the other hand has access to high percent kill combos.
