Our Verdict
TCL 6 Series/R646 2021 QLED
Amazon Fire TV Omni QLED Series 2022
The TCL 6 Series/R646 2021 QLED is much better than the Amazon Fire TV Omni QLED Series 2022. The TCL gets significantly brighter to better fight flare in a bright living room, and it allows for bright highlights in HDR to stand out better. The TCL is also much better for gaming thanks to its 120Hz refresh rate and faster response time, resulting in smoother motion with less blur behind fast-moving objects.
