I also think you need to think about what exactly you are trying to achieve and who has a "look" you really like. Plus where are you willing to travel too. For example I had mine done with Dr. Paul Shapiro. I loved the work he was putting out and he has been very consistent. And I have heard that he isn't as conservative as his bother Ron.
But I will tell you that if I was say early to mid 30's and only had frontal loss I would take a serious look at Dr. Rahal, both the Shapiro Brothers, Dr. Feller, True and Dorin, and Dr. Arocha. But if I was a NW 5 or 6 I would look at Hasson and Wong, as well SMG.
Also some only due strip (H&W) and some are leaders in FUE (Feller).
