I bought an LG CX a couple of years ago, I'd been wanting to get an OLED for some time (the problem was I use my TV for gaming and burn in possibility put me off) and the LG CX was my choice as my first OLED. At that time I owned a Sansung QLED and I was very impressed with the CX. It had everything I wanted (4K, 120 Hz, 4 x HDMI 2.1, VRR, Freesync, very low input lag, etc, etc...). Even today it's a amazing TV.
A few months back I got a Samsung S95B. I put the CX in my gaming room and now I use the S95B as my main TV, and man, it looks fantastic. It really takes OLED technology one step further. It has the perfect black and per pixel precision that I love from OLED, but it also has the color volume and the brightness of a QLED. It's a little bit like having the best things of both worlds. Really, guys, this thing gets BRIGHT!
Unfortunately Tizen is a little crappy and the OS is not on patñr with the image quality. In fact I like WebOS better, it's snappier, more responsive and has better options. Seriously, the OS still needs some work, it's not what you would expect from a high end TV. I think even my 2018 QLED ran better, to be honest. And I still think Samsung built in Media Player is the worst, you can't even set subtitles off by default, so every single time you play a file you have to manually set subtitles to off. A problem I already had with my previous Samsung TVs, I can't believe Samsung hasn't fixed it by now.
And that's pretty much all my experience with OLED TVs. I'm really happy with both of them and I don't think I could ever go back to LED technology. In fact before the S95b I bought a Samsung QN95A and I was quite disappointed, I got it as my new gaming TV and I ended up returning it a few days later after trying some games. The local dimming did some weird stuff when in game mode, the highlights became like less bright and somehow diffuse when moving the camera, if still everything looked fine, but as soon as you move the camera the highlights went to hell. Weird shit I couldn't even find on the Internet. With the S95B the situation was the opposite, I got it as my gaming TV too but I like so much that it ended up being my main TV, and I decided to use the CX for my gaming room instead.
Very happy with OLED so far overall. As I said I don't think I could go back to a LED TV, even if it's a really high end one. Maybe it's true that once you go black you never go back.
