Our Verdict
TCL 4 Series/S435 2020
TCL 4 Series/S446 2021
The TCL 4 Series/S435 2020 and the TCL 4 Series/S446 2021 are both part of the same lineup from TCL, but they have different features. The 4 Series 2020 uses Roku TV and has a VA panel with high contrast, while the 4 Series 2021 we tested has an IPS-like panel with wide viewing angles, but there are variants with a VA panel instead, and it has Google TV. The 4 Series 2021 is a better choice for bright rooms because it gets bright and has better reflection handling, and it has a quicker response time. The 4 Series 2021 also has a motion interpolation feature, which the 4 Series 2020 doesn't have, and it has lower input lag for a more responsive gaming experience.
