Samsung Q70C vs Q80C: Which TV Is Better?

The Samsung Q80C is a bit better than the Samsung Q70C. The Q80C has a much wider viewing angle than the Q70C, great for watching with friends in a wide seating area. The Q80C also has local dimming to slightly improve its contrast, although its local dimming feature is mediocre. It gets a bit brighter than the Q70C in both SDR and HDR, has better color volume, and has a faster response time with much better dark scene transitions. Otherwise, they both have the same set of gaming features.
