Our Verdict

TCL 4 Series/S435 2020

TCL 4 Series/S434 Android 2020

The TCL 4 Series/S435 2020 and the TCL 4 Series/S434 Android 2020 are variants of each other, with few differences. The S435 has Roku TV as its operating system, while the S434 has Android TV. Roku is generally easier to use, but there's a larger selection of apps available on the Google Play store on Android. Each TV has nearly the same performance, except the S435 removes 24p judder, which helps with the appearance of motion in movies. Our unit of the S434 also has much better black uniformity, but this may vary between units.
