In terms of actual ability to host... Dr. Oz is good.

In terms of who he is, just an awful voice.

Jennings was great start to finish.

Mike Richards grew on me, he was too Type A frat boy at the start but his personality quickly corrected my first impression.

What makes Katie Couric a great interviewer,is her downfall as host. She's too even keel, to perfectly professional. Jeopardy needs a host rooting for the contestants.

Then, yes, Oz. He's doing a good job, but who he is as a snake oil salesman should disqualify him.
