Mikotoba and Barnham are right there in the same tier for me. I'll go with Barnham, under the expectation he's the less popular of the two.
Barnham = Mikotoba > Yuri > Zinc > Yanni > Winston > Big Wins > Wordsmith > Wocky > Zak
Bonus points to Yuri Cosmos. He's delightfully silly and his breakdown is ace. Slight nod to Zinc for the slow-mo tumble.
