I'm more of a Yuzuki person myself. I think I liked Freya, but the Chii hate expanded to her. A shame, she's such a tragic anti-hero.

I think that happens to me with Yuuko's wardrobe. The woman is so ecclectic and elegant, unlike almost every CLAMP girl that likes clothes (Hokuto, Tomoyo, I love you, but... WTF at your outfits?)
