I got the 65". It was delivered about 36 hours ago. In that time we have already watched 2 movies (blu ray), 4 episodes of Longmire (Netflix), and 4 episodes of Dexter (blu ray). It has also been used for a lot of gaming. Batman: Arkham City looks great in 3D, by the way... Call of Duty required active 3D, I guess?
So you can see we use it a lot, but hey, I am on vacation.
Everything has been flawless except one episode of Dexter that had a couple of... I don't know the term... Like an echo of the person next to the person? But those spots were literally less than a second long each and there were only a couple. Just being thorough.
Also, a lot of people complain about the glossiness of the screen. It is much less glossy than my old Toshiba, so yay!
Here is an iPhone pic of the default "Vivid" settings that my PS3/Blu Ray player defaulted to:
