I never cared about stuff like that. I don't like both just like I don't like Britney (too many like's for me in one sentence
But I think that there won't be (for now) a singer as much popular as Britney... She was the first sweetie, blondie, pinkie, girlie singer and she was too cute to be good. So no one can be next Britney. It's impossible! (I don't say it's good to be Britney, don't get me wrong)
