Honestly, PerfectKicks has the best reps I've ever seen. They do their research and actually fix all the flaws on other rep companies shoes and then release their version, which most of the time are so close that even if you have a legit pair right next to them, it's almost impossible to tell. Their Instagram page has a ton if in-depth pictures and reviews @perfectkicksnet.
On the flip side, if you want to see flaws on other releases, check out @fake_education. PerfectKicks actually reviews their comparisons and fixes all the flaws the guy points out before putting out a final release.
I'm pretty green on the rep shoe game, but like I said, am a big authentic shoe guy with 30+ pairs of authentic Jordans, 6 pairs of authentic Ferragamo's, and about 10 pairs of Cole Hahn's. I've yet to see better "fakes" on shoes than PK.
