Our Verdict
Samsung Q70/Q70A QLED
Sony X91J
The Sony X91J is better overall than the Samsung Q70/Q70A QLED because it has more features. The Sony is only available in an 85 inch size, and the Samsung is available in 55 to 85 inch size models. The Sony delivers a better experience for watching movies because it has a local dimming feature, which the Samsung doesn't have, but the Samsung gets brighter if you want to use it in a well-lit room.
