My TV path has been interesting.
In 2015 I got LG's EF9500 after they dropped in price. OLED picture quality was jaw dropping, but since I mostly play video games the input lag, at around 50ish ms, was killer. The image quality was unreal, but I never enjoyed playing games on it. So I got rid of it and went with Samsung's FALD JS9500. The input lag was great, at about 23 ms, but for some stupid reason Samsung LOVES curved sets and after about 2 months I got sick of having a bent tv. Plus, even though FALD is a great band aid for LCD's problems, once you get a taste of OLED's goodness it's impossible to go back. I went about 7 months without a TV waiting for LG's 2016 offerings, and when the E6 had an advertised input lag of 34 ms I bought back in. The input lag was better, and I was able to play a whole lot of Odin's Sphere, Uncharted, Horizon, and Zelda...but I when I wanted to play games with a mouse/keyboard, or anything on PC with Vsync on, it became noticeably laggy. So when this year's OLEDs came out with a blistering fast 21 ms input lag I sold off my E6 real quick and got a C7. I don't regret it for a second. The input lag is every so slightly noticeable, but the reality is that TVs don't really get much faster that this.
Summary: Once you've had an OLED you can't go back. It's a HUGE jump in quality compared to anything else on the market.
