Is Jay-Z the Greatest Rapper?

I can't say his is and I can't say he isn't. Jay-Z is known worldwide. Has mad respect in mostly all circles of rap. I mean, who would say no to being on the track with Jay-Z? He's always been consistent with the flow and has a lot of stripes under his belt. The problem is, there are other rappers too who posses the same impressive resume' as Jay.  When you throw the platinum plaqes away and it all comes down to just the rhyme, Jay-Z is still there in the midst of conversation. Will he jump in and out of rap forever? Who knows? He's given the world more than enough already.
