i don't know if there is any significant difference in price between dentists as long as insurance involved, in my case i use it and it cuts doctors rate significantly, I don't imagine any doctor offers lower rate than Humana or Metlife PPO programs allow.
I've been seeing doctor for long time, sucess rate was ~90%, that means few 1 crown and 1-2 filling I have to redo and repay within 2-3 years, but I assume it is not that bad.
good equipment and service as well as location.
yes, sometimes you feel like being place on conveyer as there are 3 seat and one doctor, but then there is 1 doctor and no substitute ones as other clinics practice and whenever I needed special attention I always got it.
