Our Verdict

Sony X90J

TCL 6 Series/R646 2021 QLED

The TCL 6 Series/R646 2021 QLED and the Sony X90J are both great TVs. They each have a VA panel with a high contrast, and even though the Mini LED local dimming feature on the TCL does a better job at improving the contrast on our checkerboard pattern, the local dimming on the Sony performs better overall. The TCL gets brighter and has much better reflection handling, making it a better choice in well-lit rooms. It also has more gaming features like FreeSync VRR support, but the Sony is G-SYNC compatible. The Sony has better color accuracy, and it does a much better job at upscaling 480p content, so it's better for watching DVDs.
