Eminem is the better rapper, and Jay Z is the better businessman. Jay Z has achieved a lot more in his career than Eminem. He has sold over 100 million albums and been nominated for 20 Grammy Awards, far more than Eminem's 10 nominations. Jay Z was also recently listed as one of Time Magazine's 100 most influential people globally. At the same time, Eminem was only mentioned in hip-hop's 50 greatest artists.
