I'm pretty happy with my Samsung UN50TU7000 "Crystal UHD" 50" TV. The picture quality is, IMHO, excellent, as is the sound. There may be other more pricey versions available from Samsung, with better performance in brightly lit rooms, but I'm more than satisfied with this unit in my living room. I got it a couple three years ago and have no complaints, other than that the remote doesn't include a backlight. Oh well, that's why I have a floor lamp next to the recliner!
