TFTCentral review of the AOC version is up.

Pretty much mirrors what I am seeing with the Omen on viewing angles, motion clarity, BLB etc. Although, mine doesn't appear to have as dark of a top left corner.
It is interesting that if you remove some minor black to grey transitions, TFTCentral came up with an average GTG of 6.6ms. That would actually put it faster than the IPS 21:9 monitors. I have also semi-confirmed this, as I am getting an average of about 8ms on the MPRT test. This is faster than the Samsung CF791 and the 21:9 IPS displays. Through extensive testing, I would only recommend the setting of Level 3 (default) response time. This seems to have the best overall response under the most transitions.
The build quality on the Omen is definitely on the higher end. Use of anodized aluminum and other features such as a minimalist style thin bezel and an industrial rear housing greatly appeal to me.
My display has zero pixel issues, minimal back-light bleed (almost identical to TFT's picture), runs 100 Hz stable with G-Sync and zero physical or cosmetic flaws. I would rate it a 9 out of 10, just slightly ahead of the 21:9 IPS competition. If you have an AMD GPU, the CF791 would be the best buy.
