Which is better Rock vs. Hip Hop

Wich is better some artists from a rock background or hip hop. P.S. I know some of the people on the quiz are not hip hop but like rap or r&b. But i am putting them in the quiz and some people that are rock are actually Death Metal but i put them under rock so it is really not Rock vs. Hip Hop but more of the same background of rock vs. Hip hop. P.S.S. Sorry if my spelling was incorrect.
