I like all of them to some extent. I always see Peach get hate online but I don’t really get it. Most of the time she’s kind of boring personality wise and in 70% of mainline games she’s not much more than a plot device, but… I don’t know, I’ve always liked her the most. And the times when she is playable in the mainline games she’s always the most broken fun character to use, and I like using her in spin offs too. Daisy is pretty cool, but I think Rosalina is a little overrated even though I love Galaxy. She has a pretty aesthetic but because I’m weird I like the other two better.
I like all three, but my favorite is Daisy. I just have always liked how she was more of a tomboy. Plus, she has a nice color scheme and shares a name with my favorite flower.
