Lets see, KRS1 had his best shit when his first 2 cds came out, not saying his other shit wasn't good, but it just didn't compare to his other stuff. Battle wise though, KRS was a genius. He couldn't get touched on the mic. Pac on the other hand, is, and will be 1 of the best rappers of all time. Way better than KRS1. Pac could hit you at every angle. He hit all the problems of the world, of his life and the street life. And when he rapped, you could feel him. So this 1, in my opinion goes to Pac. Peace!
