Our Verdict

TCL 4 Series/S446 2021

Hisense A6H [A6, A65H]

The Hisense A6H and the TCL 4 Series/S446 2021 are extremely similar. The Hisense is slightly more versatile, as it has more HDMI inputs and a few extra features, including variable refresh rate support for gamers. The TCL is a bit brighter, so if you don't care about gaming features, it has slightly better picture quality and can better overcome glare.
