Sony X85K vs Samsung Q80B [Q80, Q80BD] QLED

The Samsung Q80B QLED and the Sony X85K are both good TVs with different uses. The Sony is better in dark rooms as it has improved contrast and better black uniformity. Even if the Samsung TV has a local dimming feature that the Sony model doesn't have, the Sony still looks better in dark rooms. However, the Samsung is the better choice if you have a well-lit room as it gets brighter and has a wider viewing angle if you want to use it in a wide seating arrangement.
