Wow this is an old question. And it's spelled sense, not cents.
In my opinion, I think Cat. Tori's style is kind of plain (not that it's a bad thing, of course) and she wears too much boots and belts and stuff like that. Cat's style is really cute and I think she puts outfits together very well.
Depends what あなた like, personally I like people who are out going with fashion and use a lot of color. Tori's clothes are もっと見る 'cool' and Cat's are もっと見る out there. I don't dislike Tori's sense of fashion though.
