Teeth: Obviously Ayu. Perfectly straight and white Hikki's are crooked.

Hair: Depends. Sometimes Hikki's hair looks akward and her dark hair always makes her look older than she actually is. Plus she cannot really pull off any hair colour and look stunning apart from black. Hairstyle wise I think she looks best in long and straight like in "Deep River" and "Exodus" Era. She looks really gorgeous there. I must say her Exodus hairstyle made her look simply gorgeous. On the other hand her "Be My Last" hairstyle was odd. That fringe was simply awful.

Ayu can pull off any hairstyle and look gorgeous.

Skin colour: Hmm.. Hikki's skin colour is quite appealing. Ayu's varies.. so yeah I can't really decide between these two.

Style: It depends. I think Hikki's style is interesting and appealing for older and more women in their mid twenties. Ayu's style is more appealing for teenagers and young women. I myself do prefer Ayu's style as it is more experimental and alluring for me.
