Acne Scars. Consulted several doctors!

I am Dev from Hyderabad(India), I am looking for the solution of Acne Scars on my face. I have consulted several doctors regarding my scars. Most of suggested only laser treatment, Here I am confused with which laser to be opted to treat my scars, Because most of the doctors suggested only laser which they're having them in their environment. They suggested me 6 sessions of laser treatment on my face. Now my question is which laser has to be opted or else which doctor should I choose? Doctor A= Pixel fractional laser(6 sessions) (total costing 25K) Doctor B= Er fractional laser(6 session) with subcision and RPRP (total costing 30K) (But doctor says that Er laser treatment is done by a Technician). Doctor C= CO2 laser(4 Sessions) (total costing 20k) And I am confused with Doctor B, Can I trust that technician to work on my face? Please help me with your suggestions else please prefer me any doctor good at treating acne scars with laser treatment
