If you're prioritizing cost and display uniformity in dark environments, the TCL S450F would be the more economical choice and it excels in black uniformity. However, while the Amazon 4-Series isn't as strong in dark rooms, it offers slightly better reflection handling for brighter spaces. Both models have their challenges with picture quality, so neither would be ideal for serious gaming or sports viewing. For those who may also use the TV as a computer monitor, the TCL S450F supports this better and has slightly higher speaker power. The decision comes down to whether the modest increase in certain features with the Amazon 4-Series warrants its higher price tag over the TCL S450F's better value proposition and specific strengths.

"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."

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.
