Good question. Both are dope lyricists, but while I've never heard Thought say a wack line, I would give the slight edge to Nas because of his impact on the game.
Just really started listening to Spitta this year.... One of my favorite young cats. Alot of up and coming rappers could learn a lesson from him about being independent and making music on your own terms.....
Realy anything you can find on him is pretty dope. What the f*c# is Jay Electronica, Electrochemicals. Last thing I heard from him was a song off Reflecion Eternal's Revolution's Per Minute.
