None of them.
Because they're all pretty bad.
Grisham sounds like he's not even a fan, sounds surprised when he sees a reach measurement lol.
Stann sounds like a "know it all", oh "I used to be a fighter so I know everything" guy.
Rogan is condescending and is always telling you how someone has a great chance to win, when they don't.
Anik is actually cool, but lacks any umph like Rogan and Goldberg do.
Cormier cannot commentate about anything outside of wrestling techniques and is always trying too hard to be witty.
Cruz is a genius analyst, but has a horrible voice for commentary.
Hardy gets words wrong a lot and always sounds way too involved in the fight for actual commentary.
Gooden, probably the best of the lot lol.
