If cost is your main concern and you primarily watch content in lower resolution like DVDs or standard television broadcasts, the TCL S355 could suit your needs while saving you money. However, if you can spend a bit more for a slight improvement in viewing performance in brighter rooms, the Amazon 4-Series would be a better choice. Keep in mind that both TVs are not ideal for gaming or watching sports due to lower performance scores in those areas. The Amazon 4-Series also offers better support for HDR content, which may enhance your movie-watching experience, provided you have HDR-compatible media. Neither TV is particularly well-suited for dark room viewing, but if occasional brighter room viewing and HDR support are worth the extra cost to you, go with the Amazon 4-Series. If not, the TCL S355 will save you money. Give Feedback

Tech Advisor

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."

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.
