If you're on a tight budget and want to save a little, the Amazon 4-Series could be your choice, but be aware that the picture quality is not optimal in brightly lit rooms. For general viewing, the TCL S435 provides slightly better performance, although it's not ideal for sports or video games. Both TVs have similar poor marks for use as a monitor or for gaming, but the Amazon 4-Series manages reflections a bit more effectively if glare is a concern. The TCL S435 has some advantage for cartoons and animation, and its sound quality is judged very poor. Neither TV stands out for high dynamic range (HDR) content, with limited support and unimpressive HDR performance. Both have fair upscaling ability to improve lower-resolution content but expect less vibrant colors and contrast from both models. Note that neither option is likely to satisfy if excellent picture quality or gaming responsiveness is a priority. Give Feedback

Jim Martin | May 2023
"The attraction here is that the 4-Series uses Amazon’s Fire TV interface. Picture quality is good but unexceptional. At the discounted prices, which can seemingly be had regularly, they are better value."

"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 Amazon

Amazon, the largest online retailer in North America, has forged partnerships with TCL and Hisense to produce white-label TVs incorporating their Fire OS software. These Amazon-branded TVs typically compete in the low-end and mid-range segments, offering compelling price points. Leveraging their strong reputation, Amazon has swiftly built brand trust in the TV market despite being relatively new to it. To enhance their popularity, these TVs integrate features from the Amazon ecosystem, including Alexa, providing users with a seamless and interconnected TV experience.

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.
