I'd still get the Samsung, HDR is great, but windows can't handle it in the OS anyway, and what few games exist that support it properly are... few. You don't need 1000 nits 18 inches away from your eyeballs, if you're running your monitor at that level of brightness you'll screw your vision anyway. For the money I reckon it's the best choice, I'm open to viewing OLED stuff, but there's no where I know of to go and view a decent OLED screen here, I'd likely change my mind if I saw one. But of all the screens I've seen, that Samsung is at the top until further notice. The colours and viewing angles (even on a curved screen) are simply divine.
