Why do so many people think lil wayne is the best rapper alive?

when there are artist like rakim, Talib Kweli,lupe fiaco,nas,jay-z,common,and a bunch of underground artist 10 times better than him.he is a studio gangster and his lyrics are just wack metaphors and similes like "im so___like__" or you are a___i am a__" all his songs are like that.you can say im a hater but im just speaking the truth
