Hip Hop Vs. Rock: Which is better?

And when I say Hip Hop, I mean REAL Hip Hop! Not Soulja Boy, Lil Wayne, Dem Franchise Boys or any of those other garbage pale rappers or ring tone rappers. I'm talking about REAL rappers like Nas, Eminem, Big Pun, the OLD Jay-Z, The Firm, Game, Wu Tang, Capone-N-Noreaga, the Beatnuts etc. I'm also a HUGE rock fan as well. Coheed and Cambria, METALLICA, My Chemical Romance(the old MCR though), Avenged Sevenfold, As I Lay Dying, Aiden, System of a Down, Linkin Park, H.I.M., Say Anything, Led Zeppelin, Killswitch Engage, The Devil Wears Prada, Black Sabbath, Queen, Nirvana, Pantera, Rage Against The Machine, Red Hot Chili Peppers, Suicidal Tendencies, Sublime etc. I've been listening to rock A LOT more then hip hop since like 2004 - 2005 because there isn't really any good rappers left anymore... I don't really listen to Hip Hop that much anymore actually.
