Our Verdict
TCL 6 Series/R648 2021 8k QLED
Hisense U8G
The Hisense U8G and TCL 6 Series/R648 2021 8k QLED are both great TVs with different resolutions. The Hisense is a 4k TV, while the TCL is 8k, so it supports higher resolution signals. Although the TCL has Mini LED backlighting and the TCL doesn't, the Hisense has a better local dimming feature because it doesn't crush blacks as much and has better uniformity. The Hisense also gets brighter in HDR, delivering a better HDR experience.
