Our Verdict
Samsung Q80/Q80R QLED
Samsung Q70/Q70T QLED
The Samsung Q80/Q80R QLED outperforms the Samsung Q70/Q70T QLED in almost every category. The Q80R looks and feels better-built, has local dimming, can get much brighter, especially with HDR content, has much better viewing angles, handles reflections much better, has much better motion handling, and has a wider color gamut. Its biggest disadvantage is that its contrast ratio isn't quite as high as the Q70T.
