The Samsung H8000 LED TV is a great TV, but if you don't need the curved screen, go for a cheaper model, like the H7150. It has about the same picture quality.
Overall, the Samsung H8000 LED TV is a great TV with tons of features. The curved screen is a novelty that doesn't add much to the experience, though, and the picture quality is similar to lower-end models. Therefore, unless you really need the curve, go for a cheaper Samsung model, like the H7150.
The viewing angle is quite poor. As soon as you are off-axis, the colors lose saturation. The curved screen also diminishes the experience off-axis.
Because the screen is curved, the reflections stretch horizontally. It only reflects lights that are directly in front of the TV. We had to move our background lights closer to the camera for them to be captured by the picture. The finish is glossy, so the reflections are attenuated, but more defined.
The smart features are great on this TV. It isn't as user friendly as LG's WebOS, but you can do a lot more. Check out our full review of Samsung's 2014 Smart TV platform.
