Our Verdict
Vizio SB36312-G6
Vizio M Series M51a-H6
The Vizio M Series M51a-H6 is better than the Vizio SB36312-G6. The M Series is a 5.1 setup that comes with dedicated satellite speakers. It offers better surround and Atmos performances, and it can get louder. Also, some users may prefer its more neutral sound profile out-of-the-box. That said, the SB36312-G6 does support more wireless playback options.
