Whose the best rapper ?

i am so sick & tired of hearing this Jay-Z, NAS is the best rappers alive. how old is Jay-z now? 40 years old, his beats are retarded anyways, maybe he was good in HIS time what he needs to do is stop rapping and do himself a favor. dont get me wrong i appreciate some of his music but the rappers of today & tommorow are lil wayne, drake & nikki minaj. && NAS is SOO GAY he is pretty much underground, ive never even heard of a single song from him or any albums so i dont see why people think hes so great. && seriously dont even diss lil wayne out because everyone is sick & tired of fake crips saying they hate him because they think tht crips & bloods hate each other whenever they dont even have beef.
