Joel had a better synergy with the bots and host segments.

Mike has the advantage of being around when the show started branching out into some of the more bizarre movies and thus has the most memorable episodes.

Jonah has a higher consistency overall, but is at his best tearing into demented children's films. (Cry Wilderness, Mac & Me, Munchie)

Emily has the fewest episodes but she's knocked it out of the park every time.

All in all, I see no need for host wars.

Now robot voice wars on the other hand..... Trace and Kevin.

Both

There is a good reason why Joel chose Mike to first be his head writer, then to take over his show: Mike is much funnier. No disrespect to Joel, but Mike's riffs are faster, deeper, and more rapid. I bought a "Team Mike" pair of socks on redbubble to prove it. I am wearing them now. The prosecution rests.
