The top one. The center one is too dark (looking it from a carefully calibrated monitor). Whenever you are in doubt, check the histogram of the luminosity.
The middle one is more darker, grittier, and therefore stands out agains the top and bottom pics, which are too bright in comparison. For this reason, I'd likely pick the middle one -- though of the two others, the wear-and-tear shows up a bit more on the top pic. It's a tie in my book; take your pick.
Hello fellow PVA display user Middle one is my pick too, but i learned it's destroyed by most TFT monitors :/ I guess I will go with brighter one in the end
