The best, for me, would have to be pennywise vs the joker is the best. It is so incredibly even and the burns are incredible.

The worst is a three-way tie between Bruce Jenner vs Bruce Banner, Donald Trump vs Hillary Clinton, and Thomas Jefferson vs Frederick Douglas. Why? because each one of those they were trying to send a message instead of trying to create a battle. Especially in jenner vs banner. Jenner got at least 2 minutes worth of rapping when hulk only got 10 seconds. What kind of shit is that?

Trump vs Clinton was almost just as bad because they inserted their own political bias into the role. The spirit of the battle is supposed to be "You decide". In this one though they did everything they could to paint Trump as a worse person and then have Lincoln show up to tell Hillary that she needs to win.
