This was a really tough call because both brought the ruckus, but if I had to pick one or the other then I'd have to go with "MadFLeX". I mean "Richard J. Amtmann III" was also good, but "MadFLeX" just stayed calm and cool during the whole thing and just countered with amazing lyrics. In other words, COCOCOCOMBOOO BRRREEEAAAKER!!!!!!!!
