Deep FX Vs. SmartXide for Acne Scarring

I have been to three different skin specialists, with three different recommendations for treating my acne scarring. I am torn between Deep FX and SmartXide. Are the differences between them so marginal that either one would be fine? I have a combination of different scar types (see picture); some are deeper than others. My skin is type 4 pigmentation. I would like to minimize the risk of hypopigmentation.
