Love them both in the end but the question is really clear, who's the best performer today? Britney has had amazing performances, all of her VMA's performances before Gimme More were outstanding but nowadays Britney is just not the same on stage while Rihanna has improved a lot, she might not be the best dancer or singer but she works her ass off to please her fans and that alone deserves a lot of credit and all my respect, plus she has a lot confidence on stage.
She's not the new Beyoncé, but she's definitely a better performer than Britney TODAY.
She sings better, she performs better music, she dances better, etc, etc.
She's a better singer than Britney ever was and seeing as singing entertains me more than dancing I think Rihanna has always been a better performer than Britney
