Our Verdict
Hisense U6G
TCL 6 Series/R646 2021 QLED
The Hisense U6G and the TCL 6 Series/R646 2021 QLED are both great TVs. They have similar characteristics, but there are a few differences between them. The TCL has Mini LED backlighting that allows it to get much brighter, especially in HDR, making highlights pop more. They each have decent local dimming features, but the one on the Hisense does a better job at displaying deeper blacks than on the TCL. The Hisense also doesn't have issues upscaling 480p content, which the TCL has issues. The main advantage the TCL has over the Hisense is a 120Hz panel with HDMI 2.1 inputs and VRR support, none of which the Hisense has.
