Yeah I had this on my mind recently because I was thinking whether or not I should get more BoA songs. Utada has her own style as well as BoA, so yeah saying versus just doesn't make much sense. They're distinct in their own type of Jpop. I like Utada Hikaru better obviously because I'm more of a fan of hers. That's why we're on this forum, not much sense in making a dual against them. Both are Jpop singers with their own style and have different voices with different experiences in the music industry. I listen to both of their songs. Although I must admit I have more of Utada's music so I can't say much about BoA. I do have to say though that her song OUTGROW ~Ready Butterfly~ reminded me so much of Britney Spears voice. I forgot what song by Britney, but in that song, BoA sounds a bit like her. It was interesting. Anywho, yeah I'm a Utada fan, so Utada is who I like better.
