I have the 50” Select 4K TV, for the price this is probably as good of a TV you can get. Relatively crisp image and strong colors, great sound, and fantastic interface. My gripe with this TV is when I stream YouTube TV 4K sports it defaults to an HDR mode which considerably downgrades the quality of the image relative to Standard feed (1080 HD). There’s no way to turn off HDR, and changing the settings does not fix the problem. Whites look gray, colors are extremely faded, no contrast, and poor brightness/backlight. Streaming a video on demand (instead of live sports) in 4k was actually great quality because it doesn’t switch into HDR mode. I am disappointed and hope they will add a way for us to turn off HDR or at least more options to adjust the image.
Bottom line: If your content does not need to use the “HDR” mode then don’t think twice and get it.
As the saying goes, happy wife, happy life. My wife loves this, and I too am impressed with the Roku 65" TV I bought. Set up to all our streaming services was very easy and she is loving the TV! The picture quality is great, and sound is excellent too. It's so good she hasn't even pestered me to set up the sound bar and surround sound system that was the other part of her Christmas gift!
