Our Verdict

Vizio V Series V51x-J6

Hisense AX5125H

The Hisense AX5125H is better than the Vizio V Series V51x-J6 since it supports Dolby Atmos content, which is increasingly common on various streaming platforms and Blu-rays. The Hisense is better built, too, with 4k passthrough, which is helpful for gaming. However, if you don't watch much Atmos content, you may find that the Vizio is the better deal of the two since its surround performance is quite similar to the Hisense.
