It's the lowest latency set I've ever used in "game" mode, and arguably one of the only times I can say I've truly felt the difference. I'm suddenly not terrible at CoD since getting it, and quite literally every game I've sampled so far feels more responsive than ever before. It took a bit of fiddling to get the image how I wanted it, but it wasn't overly tough. YMMV though, as I work with colour/imaging for a living and likely have a more keen eye than average. I find that Samsung screens tend to veer toward the cool side of things, but there's enough finite control that it can be corrected and set up to your personal preference very easily. I haven't noticed any issues with HDR outside of Monster Hunter, but again it's my first HDR set.
Also, aesthetically it's one of the nicer tv's out there right now if that matters to you. It sort of reminds me of the current iMac style as far as shape is concerned. I prefer the hard corners of the Sony stuff, but the insane thinness of this combined with the excellent cable management system is absolutely gorgeous given that I have it on a clean, minimal tv stand. I'd never seen the "one connect" box before (all your inputs and outputs are on a separate box rather than on the back of the actual tv) and already don't know if I could go back to anything else, as I'm able to keep it tucked away in of of the sections of the tv stand, keeping the wires spilling out to an absolute minimum.
