It's hard to say, I always prefered 2nd Round KO because most of LL's punchlines was eating off 2nd Round KO, but LL had alot more intensity to the track.
My media standards, LL won it, because Canibus is not as big as LL, but by lyrical standards, I'd give it to Canibus, but LL was very close.
It was a great battle, to bad there aren't many like that anymore.
