Is Fraxel or Photodynamic Therapy Better for acne Scars?

I have very strong active acne. What is the best option in my position? Should I use a fraxel laser or should I go with the photodynamic therapy? Is one better than the other for live acne as opposed to scaring? I think that is what I need to figure out. What are the major pricing differences between the two as well.
