What type of laser would best help me get rid of the coloration in my scars?

So far I've had two dermapen treatments why have failed in improving the discoloration within my scars so I plan on getting a laser afterward. Ignoring the fact that some of these are indentations and if my primary goal is to achieve even skin tone. What laser would be deemed best for me? My doctor suggested V-beam or E-matrix but I would like a second opinion. On a side note, if I also plan on getting chemical peels which one would be safest for my skintone TCA, Glycolic, Salicilyc or Vi Peels.
