The LG LB6300 LED TV has the best smart TV OS, low input lag, and a great viewing angle. Unfortunately, it has low contrast and reflects a lot of light, so its picture quality isn't up to par to TVs in its price range.
The LG LB6300 has a design very similar to the LB5800, except the back has the same gray finish as the borders.
The main selling point of this LG is the smart TV interface called WebOS. It is indeed the most user friendly smart TV that we tested. Check out our full review of LG's 2014 smart TV platform.
