The Sony W800B is a really good TV for gamers. Its only major flaw is the loss of color saturation when viewed at an angle.
If you are a gamer, this is the TV for you. With its unique backlight strobing mode and very low input lag, it is a solid choice for video games. It also has very good picture quality for other uses, but if playing video games is not your primary purpose for this TV, you will be happier with either the Samsung H6350 or the Samsung H7150, depending on your budget.
As expected with an LED TV with such great contrast, the colors change when viewed at an angle. They lose saturation and become whiter.
It also performs well in a bright room and can get bright, but some TVs like the Samsung H7150 can get a bit brighter. Unless you have a veranda, though, the Sony W800B can get bright enough.
Unfortunately, the smart TV features are not very good. They do the job, but they are slow. Check out our review of Sony's 2014 Smart TV platform.
