A plastic surgeon with CO2 Candela CORE laser-full ablative or a dermatologist with CO2 Lumenis UltraPulse full deep fractioned?

I am 34 year old man. I am looking to get full laser C02 resurfacing on my face for *moderate* acne scaring, light wrinkles, discoloration, and overall rejuvenation. I want the absolute strongest, most effective, gold standard laser treatment on the market and downtime is of no concern as I get laid off in the winter. The problem I am having is the differences in Doctors, the technology offered, and their opinions about treatment. It's so bad I literally have *TWO* resurfacings scheduled next month
