While it is true there are many good comedy magicians, I think a few things set Mac King apart. First, he has one of the longest-running shows of any kind (and in the same venue) in Las Vegas. Second, his show is a rarity in that it is both suitable for everyone and entertaining for everyone. Third, his talent is recognized not only by other magicians, but by the entertainment industry at large. His act has been voted "Best in Las Vegas," in a number of different categories. Finally, he is consistent as a performer and consistent as a nice guy. I've read hundreds of comments about his show and have yet to hear a tale of how he had a bad day or an instance in which he mistreated someone.
There just aren't a lot of people that can match all that.

I was surprised that Bill Malone wasn't in the list that was just recently released by Magic Magazine. I haven't read the article yet, so maybe there was some criteria he didn't meet. I love his self-deprecating sense of humor.

Edit: I just read that he was nominated, just didn't make it in the top ten.
