In a Beauty contest: Misty and Delia
In a cuteness contest: Misty, Delia and Sakura

My opinion
Misty: Her hair, her figure, her Pokemon, everything especially her fiery spirit
May: cool girl, I kind of like her design and her Pokemon party is pretty awesome.
Delia: her cuteness, her Mr Mime, her hair, her house
Sakura: her hair color, her Espeon, her family and her house. I kind of hated Sakura at first but now she's okay.
