Our Verdict
TCL 5 Series/S546 2021 QLED
Hisense U6/U6H
The TCL 5 Series/S546 2021 QLED and the Hisense U6/U6H are both good budget-friendly TVs. They have many of the same features, but the Hisense delivers better overall picture quality because it has a better local dimming feature, upscales lower-resolution content well, and has better out-of-the-box accuracy than the TCL. However, the TCL is better for gaming because it has better motion handling.
