If you're looking for a more budget-friendly option, the TCL S450G is significantly less expensive than the Amazon 4-Series. However, you'll get better dark room performance and contrast with the Amazon 4-Series. Both TVs have poor overall picture quality and gaming performance, which is worth considering if you're an avid movie watcher or gamer. The TCL has better sound quality with higher speaker power, and it offers more accessibility through voice commands. The TCL supports most HDR formats including Dolby Vision and HLG, which could be a deciding factor if you consume a lot of HDR content. Both TVs are not ideal for bright rooms, but the Amazon 4-Series performs slightly better in this regard. If price is a primary concern and you need the additional HDR support, the TCL S450G might be the better choice. However, if contrast is more important for your viewing needs, and you're willing to spend more, consider the Amazon 4-Series. 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."

"TCL, though, has built much of its success on affordable sets, and the 2023 TCL S Class S4 with Google TV is a testament to just how good of a TV you can get for an affordable price tag"

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.
