Something I found interesting is that a YouTuber, Viktor's Reality, did a side-by-side test with the G8 and G7. He said he didn't see much of a difference in picture quality/sharpness between the two panels despite the aggressive AR film.
I really like the QD-OLED but the 21:9 aspect ration and the fact that it was 1440p wasn't the best about it. Overall, I prefer the Odyssey Neo G8 to the Alienware. I'm just waiting on a firmware update at this point to fix some of the issues.
