Our Verdict
Vizio P Series Quantum 2020
TCL R635
The Vizio P Series Quantum 2020 is a bit better than the TCL R635. The Vizio has better reflection handling and color accuracy, as well as lower input lag and faster response time. On the flip side, the TCL can remove judder from all sources, its internal speakers sound better, and its backlight's high flickering frequency causes less motion duplication in fast-moving scenes.
