Whos the best rapper eminem or lil'wayne?

Okay Eminem he has been in this rapping game for ever right...but everyone know's he had got into an issue with his drug adiction and it had got really bad very badly. but he has come back on his feet with new rhymes and ready to give it up on his rhymes. but here goes lil wayne doing his thing with his 6 foot 7 foot video and ft in it j millz and then he has his other song called how to love and his tour our coming up and hr's really out here doing his thing. all i have to say is you decide who should go on tour with rick ross!!!!!!!!!!
