Hmm..

Better Singer: Rihanna
Better Performer: Rihanna
Better Dancer: Rihanna

I guess... one already won.

Katy

Katy, Rihanna is OK but Katy can write and play instruments. Also she's the better singer and puts more soul into her singing.

Rihanna, although Katy has shown she is kinda a force to be reckoned with

This seems really bias though.

I agree with this.

Rihanna is the better singer and performer.

in b4 people pretending Katy's lyrics require "talent" to be written

EDIT: I'm late.

Katy...she's more involved in the creation of her music

Katy can write and play instruments is the main factor of why I chose Katy. Even though Rih is the better dancer shes still not that good, and Rih is a more consistent vocalist, but when Katy's on she is ON.

what soul would that be sis

Its not bias.. its Fact.

U want me to give Katy Perry .. songwriting? Ok she can have it.
Rihanna is still a model, fashion DESIGNER and actress.

Katy's the better writer, but Rihanna's the better singer and performer.

This is so close minded.

Katy can write fun silly pop songs but she can also be quite deep, sincere and soulful.

Katy writes her own music, plays multiple instruments, and actually has co-produced some of her songs. Katy clearly wins. That being said Rihanna is the better performer, but Katy's been getting better at performing live recently.

Katy wins

Well if it's that easy why don't other pop stars write lyrics to 'their' songs for themselves?

It brings in $$$ and could help you debut on certain prestigious magazines

Rihanna is the better performer, but Katy is more talented in almost every other aspect.

Katy is more talented.

.

I love them both but Katy.
