Mc's Reaper obviously had better multis and a better flow in my opinion. Only problem was some of his metaphors were stretched a little too much. I really liked:
"Poppa doc can only suck, like 'sluts paralyzed' from the neck-down..."
That was a nice line.
Popa doc just had generic shit about dude's dick being small and even when he got personal the pucnhes weren't that strong (his opener for example.) Flow was ok, but I think Mc's was a little better.
All in all a close battle, but I've gotta give my vote to Mc's Reaper.
