Our Verdict
Hisense U8G
TCL 6 Series/R646 2021 QLED
The Hisense U8G and the TCL 6 Series/R646 2021 QLED are both great TVs. They're fairly similar overall, but there are a few differences between them. Even though the TCL has Mini LED backlighting, the Hisense has a better local dimming feature because it doesn't raise the black level as much when there are bright objects. The TCL has better contrast, but the difference isn't as noticeable with real content. The TCL also gets brighter, but the Hisense has better reflection handling. While the Hisense uses Android TV and the TCL has Google, they're very similar, and the only differences are aesthetic.
