Our Verdict

Vizio M Series M51ax-J6

Hisense AX5125H

The main difference between the Hisense AX5125H and the Vizio M Series M51ax-J6 is the number of height channels. While the Hisense has two up-firing channels built into the bar to simulate height with content like Dolby Atmos, the Vizio relies on front-firing channels to perform a similar function. Still, there isn't much difference between the two's overall immersive feel. The Vizio ranks higher because it has more sound enhancement features and offers better latency.
