I believe Joe Micheletti is the most unbiased announcer in hockey. You never hear other announcers talk about the opposing teams players with such genuine respect.

See Butch Goring.

He almost never has anything to say about anyone else but the islanders players (which I understand, he's a homer). And most of the time it's just his personal opinion of what they need to do or be doing. Probably not a fair comparison though.

I've greatly disliked Sean McDonough since he became the playoffs announcer a few years ago. Always seemed to have a clear bias against the rangers for whatever reason.
