Yeah, they kind of are in different categories, Ayu probably has a much larger fanbase, and I'd rather say I'm an Ayu-fan than a fan of Utada...But this performance was so good! And then when I see some of Ayu's performances, which are not good... Well, to say it this way, I still haven't seen a performance from Utada where here voice was really bad or out of tune..But from Ayu, I have seen quite a few... Nevertheless, she has had some awesome performances too
And even though her voice might not be as good as Utadas, her image and appearance is a true superstar. Utada is more of the shy type of person...As I see it
