I would much rather be a Rocker.
1. Rockers are cool, rappers are embarrassing.
2. Rockers are talented and can play instruments/sing, rappers (generally) can't play any instruments or sing.
Just my opinion rap fans! Calm down!
I actually hate Country music and Classical music (i.e. Beethoven, Bach etc.) but at least I respect their musical talent. Rappers don't have "much" talent. They TRY (and I emphasize try) to sound mean while chanting rhymes, have gang wars and shoot people. Once again I'm generalizing... I realize that not all rappers act this way but most of them do. I also realize that rockers aren't saints by any means but most of them after a certain number of years jail terms and drug abuse either die or try to get help. (generalizing people, not everyone fits in these scenarios)
Jim Morrison vs Tupac = Tupac
Iggy Pop vs Lil Wayne = close but I'm going with Iggy (he's small but totally nuts, I think he'd go crazy)
Mick Jagger vs Khalifa Wiz = Mick Jagger by default. I don't know who Khalifa Wiz is (never heard of him)
Those of course are just guesses as I have no idea how tough any of them actually are.
Just my .02
