Our Verdict

Samsung Q80C [Q80, Q80CD] QLED

Samsung Q70D [Q70, Q72D] QLED

The Samsung Q80C QLED is mostly better than the Samsung Q70D QLED. The Q80C has a wider color gamut and better color volume, so it displays a wider range of colors at higher brightness levels, with less banding. The Q80C also has a much wider viewing angle, making it a better option for use in a group setting. The Q80C also displays slightly deeper blacks, and it has a faster response time for less blur behind quick-moving objects. However, the Q70D gets brighter in HDR, and it's more accurate in both SDR and HDR.
