To me he's not better than Pac, Biggie, Nas, Kanye or even Nicki. He wouldn't have the acclaim if he wasn't caucasian. I swear people only started siting him as "best of all time" after Rap God which is funny because it's unlistenable lol
Because to me and a lot of people who actually listen and appreciate rap music, 2 Pac and Biggie's voices are more valuable than that very overrated white guy. Since this is based on sales and not influence I guess it's fair.
