Who’s The Greatest Rapper of All Time?

So while perusing the internet this morning on my Blackberry Playbook (#TeamBlackberry all day) I came across this tweet via New Era (@New_Era_Caps)

So it got me to thinking; who is "The Greatest Rapper of All Time"?

I know you all have the answers, so the floor is yours. Who is the Greatest Rapper of ALL TIME?

I do know who ISN'T the Greatest Rapper of All Time lol
