I'm fairly unchanged.
1. David
(huge gap)
2. Jeff
3. J.D.
4. George
(even huger gap)
5. Steve
6. Brad
Steve isn't terrible so far, his voice isn't THAT bad...but he looks really dumb holding the mic as opposed to leaving it on the mic stand (why did they put a cordless one up there anyways?), and his voice reminded me of Brad from time to time...we'll see what happens over time...
At the same time, didn't Brad hold the mic as well? (Most of us hated Brad doing the on-screen part anyway)
What I feel Jeff has that David doesn't is that Jeff meets the sidekick variety Great Uncle Producer Mikey wants. David has the announcer thing well down. Jeff and David have both shown that they are Loyal Fans and True of the Price is Right, which should be included, but people like George Gray, JD Roberto came out of absolutely nowhere. I mean, the two are former game show hosts (with very short-lived shows).
My pet peeve with George isn't his announcing, but the fact that he is not wearing his signature glasses. He honestly looks better on camera with those glasses. Without him, he seems pretty dull.
