Here are some new ones I've got.
I would go for Peachette recently.
I mean she's the dumbest idea ever. She's so out of place. I don't really like her that much when I would like the real deal that is Peach herself to be playable. But I have to live with it and be happy that she's the closest thing to a playable Peach but with a pint of Daisy in it in NSMBU Deluxe (unless Peach ends up playable after being rescued in the port) or wait until New Super Mario Bros. Switch.
I just realized that I do not like Rosalina in Super Mario 3D World because of how really slow she is. She's like Christopher Belmont speed (in Castlevania: The Adventure). I mean I prefer Peach because she's faster than Rosalina. I like Peach and Daisy when they're playable because I like their abilities. I would hope that Daisy would end up in a 3D World port for Switch soon. Daisy could've been a better choice than Rosalina for a second female playable character. I don't mind Peach's slight slowness at all. It never bothered me at all. Her high jump and floating made up for it.
