Our Verdict
Samsung Q80D
Samsung Q70D
The Samsung Q80D is better than the Samsung Q70D, as it offers a noticeable upgrade in every way. The Q80D has a local dimming feature, giving it way better contrast than the Q70D. The Q80D is also brighter in HDR and SDR, and has better color volume, so all content is more impactful on that model.
