Our Verdict
Samsung AU8000
Vizio M6 Series Quantum 2021
The Samsung AU8000 and the Vizio M6 Series Quantum 2021 are both decent TVs. The Vizio uses quantum dot technology, so it displays a much wider color gamut, and it also has VRR support, which the Samsung doesn't have. The Vizio also has much better contrast, but this can vary between units. The Samsung does a better job at upscaling lower-resolution content, like from cable boxes, and the built-in Tizen OS is a better smart platform than the Vizio SmartCast system.
