Finally replaced my Pioneer 5020 with the 55 X950G. I'm very impressed. I bought a budget TCL at first based on several Youtube reviews recommending that option because the value and claims of similar performance. Well, that didn't last long - TCL returned. The X950G was just over my budget, but couldn't resist.
I've been adjusting the various settings while re-watching the same exact scenes over and over (driving my wife crazy), but after a few days of that, my settings are almost exactly what others have posted in the thread for Netflix.
For cable, I have xfinity, and it's a secondary wireless box, so the signal isn't very good. The image was very robotic, or seemed in fast motion. I was able to mitigate that by turning Cinemotion off, Smoothness max, Clearness Min. This looks the best for sports and the news for my signal. For some cable tv shows with a quality image, these settings create a soap opera effect, which I can adjust the Smoothness down a few notches and it's perfect.
The blooming issue and "value" compared to other TVs almost prevented me from buying this, but I'm so glad I did. I'm amazed by the picture.
