Opt for the TCL S455 if you're looking for a budget-friendly TV with better gaming response time and color consistency across different scenes due to its excellent black uniformity. However, if you rely heavily on smart features and prefer the integration with Amazon's ecosystem, the Amazon 4-Series could be a good fit despite its higher price. Both models struggle with picture quality and brightness, making neither ideal for very bright rooms or viewing HDR content. For casual viewing, talk shows, or as a secondary screen, the TCL S455 might provide a better value due to its lower cost. Neither TV is particularly well-suited for sports or gaming due to poorer motion processing, so if these are priorities, consider investing in a higher-quality set. Give Feedback

"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."

"A highly affordable but reliably kitted-out 4K Roku TV that, while far from perfect, still punches above its price and delivers a great user experience. If you want to soup up movie night for a bargain, the 4-Series won’t let you down. You may never need to plug in a set-top box or streaming device."

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.
