If you're looking for an affordable option and you mainly watch TV shows in a room that isn't too bright, then the Amazon 4-Series could suit your needs, but it has limited picture quality across various content, including movies and sports, and it doesn't perform well in a bright room. On the other hand, if better picture quality is important to you and you enjoy different kinds of content like sports, gaming, movies, and are willing to invest more, then the Sony X85K with good overall performance, including in bright rooms, might be worth the extra cost. The Sony also has better sound quality and motion processing which could enhance your viewing experience, particularly for action-packed content or sports. However, for pure gaming purposes or if you have a very tight budget, you might not find the additional cost of the Sony justified. 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 Sony
Sony stands as a highly experienced and widely trusted TV manufacturer, earning a reputation that surpasses all others. A Japanese company, Sony has been making TVs for far longs than it has been making Playstation game consoles. Sony's high-end TVs are often regarded as the ultimate choice for videophiles, representing the epitome of quality, albeit at a premium price point. Renowned for their advanced and precise motion handling, as well as their cutting-edge local dimming algorithms, Sony consistently delivers unparalleled performance in these areas. They include Google TV software with all their TV sets, which grants access to the largest selection of apps available and they also include Bravia Core which is a movie streaming platform specifically for Sony TVs that offers higher picture quality by using more bandwidth.
