Britney is definitely the bigger Icon.
With Beyoncé, she's popular, and has some great songs, but I don't feel like she's done anything revolutionary. Sure she has the SL video, but that's really it, and no one really talks about it anymore.
I feel like Britney had bigger impact 10 years ago, which makes her a bigger household name.
I do love both though
