They're awesome. I think Hardy is great as the color guy, different from Rogan but pretty enjoyable.
The one that stands out to me is John Gooden, honestly. He's still new and getting into a rhythm, but putting aside all that, it's so nice to hear a play-by-play announcer for the UFC who actually knows a damn about MMA and is obviously passionate about it. He certainly doesn't have the caliber of knowledge of a former fighter like Brian Stann, KenFlo or Hardy, but I think it's obvious that Anik & Goldie (can't stand anik, but I like Goldie, maybe just since he's such a fixture) are broadcasters first who have learned to observe MMA and narrate the action, while Gooden is an MMA fan and martial arts practitioner who also happens to have gotten into broadcasting. That came through to me the first time I heard him, and I'm a fan of his just on that, it makes the overall quality of the analysis and commentary higher when both guys know what they're seeing.
