Eminem - Awesome
Lil Wayne - Can't rap, he's just mumbling some words to a beat.
Kanye West - Auto Tuned asshole.
Drake - More of a singer than a rapper.
You definitely gave some bad choices. Eminem could have won if he didn't make those racist recordings. Drake is more of a singer. The others can't rap. I vote Kanye, since he is a better entertainer. He doesn't have skill, but can write. His performance on award shows is great. It got Taylor Swift a grammy from people feeling sorry and many LOLz from me.
