Tca cross or other recommended procedures for acne scars on cheeks? (Photos)

I have acne scars on my cheeks that have moderately improved with tca cross, a subcision and filler, profractional laser, and erbium fully ablative laser, but I still have some residual marks. They appear to be ice pick and boxcar scars. I went to a derm consult who stated that my scars did not appear tethered. She thought that another profractional laser would help. I'm wondering if you'd recommend another round of tca cross or c02 laser instead, or agree that profractional is the best route.
