If you're on a tight budget, the Amazon 4-Series might be appealing due to its lower price. However, it's important to note that the Vizio M-Series offers better performance across most content types, including movies, sports, and gaming. The Vizio M-Series also provides superior picture quality in both dark and bright rooms, along with better sound and motion handling capabilities. If these aspects are important for your viewing experience and you don't mind spending a bit more, the Vizio M-Series would be the preferable choice. Keep in mind, though, that neither TV excels in bright room conditions, but the Vizio fares somewhat better. The Amazon TV may fall short in overall picture and sound quality, which could impact enjoyment of various content. 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 Vizio

Vizio is an American company. While they initially gained recognition for offering budget-friendly TVs, they have successfully expanded their product lineup to include high-end options as well. They manufacture TVs primarily in Mexico, China, and Vietnam. Similar to many Korean TV brands, Vizio developed its own smart TV software called SmartCast. In the past, SmartCast was not the best smart TV software, but it has evolved so that it is now good for using your TV and connecting to streaming services.
