Microneedling Vs. Profractional Laser, best for anti-aging?

I'm wondering what the difference is between Profractional laser and Microneedling. I know one is a laser and one isn't but which is better for antiaging? i'm in my mid 40's light caucasian with good skin. I've had a medium profractional before and it was good. Also can you do PRP with Profractioal? How do these treatment results compare? thanks!
