Man this is a hard one..
All I can say is this. It depends on what you're focusing on.
If you're focusing on the context of the lyrics, I would say that MadFlex was the victor by a nose. I kinda just took off in his last verse...
If you're focusing on delivery and rhythm(like I tend to do), I'd say that Cynic was the victor.
So take what you will from that :)
