I've got the Samsung Odyssey G65B 32". Upgraded from a 165Hz IPS AOC AG271QG. So far so good. It's definitely much faster response time and it's so smooth as long as I can maintain the FPS high. Though mainly the colors and contrast stand out the most. I was worried about QC issues but did not notice anything out of whack yet. The only annoying thing which I'll probably never use is the built in Tizen OS to make it work more like a TV. I think that's just unnecessary. I did not even bother to connect it to network.
What a pleasant cozy setup. How's the motion clarity? I also see it supports HDR. How does that look?
