Which is more effective: Venus Viva or Microneedling for pitted acne scars?

I met w/ 2 diff. doctors who suggested 2 diff. solutions for pitted acne scars. One recommended the Venus Viva (which, I understand does include needles) and another stated that microneedling is more effective and/or will have same results. I already get microneedling sessions and understand it's a slow process but do get results. I'm curious if Venus Viva creates better results or should I stick to microneedling. (CO2 lasers, etc. have caused more scarring from past tx and not an option)
