Our Verdict
Vizio M6 Series Quantum 2021
Vizio V5 Series 2021
The Vizio M6 Series Quantum 2021 and the Vizio V5 Series 2021 are both okay TVs. The M6 is higher up in the Vizio lineup than the V5, so it has a few more features like a wide color gamut and VRR support. Picture quality is similar as they both have high contrast, lack local dimming, don't get bright, and have good reflection handling. Choosing one over the other comes down to whether or not you need the extra gaming features on the M6.
