Vizio 40 & TCL 40 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Vizio 40 rather than the TCL 40.

Why Do I Recommend The Vizio 40?
- The Vizio 40 comes with Apple AirPlay support for seamless wireless streaming from iPhones, iPads, and Macs directly to the TV, while the TCL 40 uses Google Cast without native Apple AirPlay integration.
- Vizio 40 features Apple HomeKit compatibility for centralized smart-home control within the Apple ecosystem, whereas the TCL 40 supports Google Home instead of HomeKit.

- Vizio 40 comes with DTS audio processing for wider soundstage and clearer dialogue on built-in speakers, while the TCL 40 uses Dolby Digital without DTS support.
- It features a thinner and more minimal bezel design for a cleaner, less distracting look in small rooms, whereas the TCL 40 uses a thicker budget-style frame.
