If you're on a budget, the TCL S435 is significantly less expensive and offers decent performance, especially for cartoons and animation. However, it has limitations in dark room performance, brightness, and gaming. In contrast, the Vizio Quantum Pro costs more but delivers superior performance in bright rooms, gaming, and has better sound quality. It also supports advanced HDR formats like Dolby Vision and HDR10+, which improve the picture in high dynamic range content. If cost is less of an issue and you're looking for a better overall experience, especially if you watch a lot of movies, sports, or play games, the Vizio Quantum Pro is the better choice. If saving money is your priority and you mostly watch TV shows, news, or cartoons, the TCL S435 will suffice. Give Feedback

Conversely, the Vizio Quantum Pro offers a better array of colors and good grey uniformity but falls short in contrast and black uniformity, compromising the richness of dark scenes.

Although they have very similar scores, PerfectRec considers Vizio Quantum Pro (LCD) to be only fair for sports, while the TCL S435 (LCD) is poor.
The TCL S435 has poor motion processing and response time which can lead to blurry images during fast sports scenes, while the Vizio Quantum Pro with very good response time and fair motion processing handles fast motion better, reducing blur and providing clearer pictures during sports. However, the TCL S435 has poor reflections handling and a narrow viewing angle making it less ideal for bright rooms and wider seating arrangements, whereas the Vizio Quantum Pro has very good reflections handling and a wider viewing angle, better accommodating different room conditions and seating.

"The TCL 4-Series is so inexpensive and capable you might start to question why there are any multithousand-dollar TVs at all. The 4-Series setup is intuitive and easy. If you're just looking for an easy-to-use TV with decent picture, this is an excellent place to start."

About TCL
TCL, the highly recognizable TV brand from China, has firmly established itself as the second-largest manufacturer in terms of sales volume. Renowned for striking an impressive balance between affordability, picture quality, and design, TCL TVs deliver a compelling overall package. While they have traditionally excelled in the low-end and midrange TV segments, TCL has recently made remarkable strides in the realm of high-end televisions, introducing impressive models that rival top competitors. Most TCL TVs use Roku software which is very user friendly and easy to use, but they have a few other models that use Google TV which has the largest app selection, but is not as user friendly as Roku.
About Vizio
Vizio is an American company. While they initially gained recognition for offering budget-friendly TVs, they have successfully expanded their product lineup to include high-end options as well. They manufacture TVs primarily in Mexico, China, and Vietnam. Similar to many Korean TV brands, Vizio developed its own smart TV software called SmartCast. In the past, SmartCast was not the best smart TV software, but it has evolved so that it is now good for using your TV and connecting to streaming services.
