If you're on a budget and prefer to save money, the TCL S450R is a more affordable choice, but it offers only fair picture quality across various contents like movies, sports, and gaming. Its performance in bright rooms is also fair, meaning it's not the best choice for places with a lot of ambient light. The Vizio MQ6, on the other hand, costs more but offers better picture quality, with good performance in dark rooms and for watching movies. It also has better sound quality, although neither TV has great speakers. Both TVs are similar in that they have a 60Hz LCD screen and support voice commands, but if you want a slightly larger screen, the Vizio offers a 55-inch display compared to the TCL's 50-inch. Consider how important picture quality and room brightness are to you compared to the price when making your decision. Give Feedback

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.

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.
