If you prioritize cost savings, the Amazon 4-Series may be suitable as it is more budget-friendly. This TV, however, struggles with picture quality across various content including movies, sports, and gaming, and it doesn't perform well in dark or bright rooms. Contrast is passable, but overall image performance and features are limited. In contrast, the TCL R646 commands a higher price but offers substantially better picture quality, supports advanced gaming at higher frame rates, and provides impressive performance for all types of content including sports and movies. It shines in both dark and bright environments and excels with HDR content, making it a versatile choice for a more engaging viewing experience. However, if wide viewing angles are important to you, the TCL R646 may not be the best fit due to its limited viewing angle performance. 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."

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.
