Our Verdict
Hisense H9G
TCL 6 Series/R646 2021 QLED
The TCL 6 Series/R646 2021 QLED and the Hisense H9G are both great. They each have VA panels that display deep blacks, but the local dimming feature on the Hisense is much better at improving the picture quality in dark scenes with minimal blooming. Motion looks smoother on the Hisense thanks to the quicker response time, but the TCL has more gaming features like two HDMI 2.1 inputs and VRR support, meaning you can use the current-gen gaming consoles to their full capabilities. The Hisense is a better choice for watching DVDs because it doesn't have issues upscaling lower-resolution content the way the TCL has.
