Our Verdict
Vizio V Series V51-H6
Vizio M Series M213ad-K8
The Vizio V Series V51-H6 is more versatile than the Vizio M Series M213ad-K8. The V Series looks pretty different than the standalone M Series—it adds a dedicated sub and two satellites to the package. It means it can reproduce a more extended low-bass and performs much better with surround sound. That said, the M Series' standalone design is ideal for those without much space. It supports Atmos content, too, unlike the V Series.
