The TCL S450G is a more budget-friendly option with decent overall performance. It might not serve well in a dark room or offer outstanding reflections handling. The Vizio MQ6 ‘23, while somewhat more expensive, offers a better picture and sound quality, with improved performance for movie watching and using as a monitor. However, it still might struggle with reflections in a bright room. If price is a key concern and your viewing conditions are not too challenging, the TCL could serve you well. But if you're looking for higher quality for a range of content, including movies, and don't mind spending more, the Vizio would be the better choice. Give Feedback

The Vizio MQ6 '23 (LCD) is good for movies & TV, while the TCL S450G (LCD) is poor.

The Vizio MQ6 '23 (LCD) is good for news, talk, & other TV, while the TCL S450G (LCD) is poor.
The TCL S450G shows news and TV programs poorly due to low SDR brightness and less accurate colors out of the box, which are vital for clear and vibrant content display.

The Vizio MQ6 '23 (LCD) is only fair for bright room, while the TCL S450G (LCD) is poor.
The TCL S450G struggles in bright rooms mainly due to its low SDR brightness and only fair handling of reflections, which can lead to images appearing washed out in well-lit conditions. The Vizio MQ6 '23, on the other hand, has good SDR brightness and similarly fair reflection handling, making it more suitable for viewing in brighter spaces without as much loss in picture quality.

The Vizio MQ6 '23 (LCD) and TCL S450G (LCD) are both only fair for sports.
The TCL S450G exhibits excellent response time which is ideal for sports; however, it's hindered by its limited motion processing abilities and less effective reflections handling that may affect viewing in bright rooms. Conversely, the Vizio MQ6 '23 offers better motion processing which can enhance the viewing of fast-moving sports, but similar to the TCL, it struggles with reflections and has a narrower viewing angle which could be a disadvantage in wide seating arrangements.

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.
