The problem with the internet is parallel to its greatest achievement: it has given the little man an outlet where he can be heard. Most of the time however, the little man is a little man because he is not worth hearing.
Eh, I prefer NicePeter's videos, but that's just me. Maybe it has to do with me not knowing of either of those two people? O.o Who are they, and why haven't I ever heard of them before?
Its probably more about what attracts you to the art. Nicepeter is more about the fun and the entertainment. Its not really a battle at all. ERB is to rap battles what professional wrestling is to MMA. The two people in the other videos were competing, showcasing their skill and their cleverness.
