This was a pretty sick battle. I can tell you two's have a good record.
Opener - Regulator - That Kleenex line was sick.
Punches - This was about even
Meta4's - Gambino- the lil john and teasure chest lines were clever However 'I'll treat you like mechanical pencils and fill you with lead' sounds familiar
Flow- Regulator had better flow but it tended to be in sections instead of linking together.

Overall it was close but Regulator has a better stucture and the Elderly-Citizens Pooping line made me laugh.
