Vizio M Series Quantum 2019
Vizio M8 Series Quantum 2020
Overall, the Vizio M Series Quantum 2019 is a bit better than the Vizio M8 Series Quantum 2020. The M Series Quantum 2019 has a better contrast ratio and local dimming, faster response time, and significantly better black uniformity. However, if you're planning on playing video games, the M8 Series Quantum 2020 has much lower input lag and variable refresh rate support.
