Cyrus vs Arc was good. But my top three were Poe vs King, Lance vs Ruth, and Zeus vs Thor. Woman wise, Cleopatra vs Marilyn was a killer. The Hitler vs Vader ones progressively lost steam. The first was epic though.

I'm not sure if you saw this, but Watchmojo.com runs a countdown series called "TopX", which is counting down the top ten things of youtube ranging from various subjects. Anyways, this video specifically catered to the Epic Rap Battles of History and what they thought the top ten ones were. Thought you'd be interested to watch and see if any of your favs made the cut.
