Much to my surprise, I just purchased a 65" Q80. Was not in the market for a Samsung at all and was leaning towards the LG OLED65B8 which was actually available a little bit cheaper but would have been from Amazon which I'm not crazy about.
I went to Best Buy after narrowing down the TV's I wanted to consider. The OLED undoubtedly has incredible blacks but there were two features in particular that swayed me towards the Q80. First of all, this is in a living room with a lot of windows all over the place. The reduction of reflections on the Samsung seemed really quite excellent compared to anything else I saw including the LG OLED(C9 was on display). Although not side by side, the blacks on the Q80 appeared VERY VERY good. Maybe they aren't as good as the OLED but I don't know if the difference is large enough to matter much. The other feature that swayed me was the ability of the Samsung to be much brighter.
My thought is that between the reduction in reflections and the brighter display, the Q80 might have an overall better viewing experience than the OLED. Maybe at night when its quite dark the OLED would come out on top, but I'm hoping that the Samsung is good enough that I won't look at it and think, man, I should have gotten the OLED. In Best Buy with unknown image settings, playing different media and the TV's spread apart, I can't say the OLED seems drastically better.
Anyone have a strong opinion about how close these two TV's are? Bought it from Best Buy but returned it and bought it off Samsung website when I poked around and found a really good deal, TV trade in discount, 6% e-bates, free shipping, and my cash back card. Saved almost $400 vs Best Buy.
