If you frequently watch movies in dark rooms, the Vizio MQ6 '23 with better dark room performance might be more satisfying than the TCL S450F. For gaming, neither TV excels, but if you play occasionally, either will suffice. The Vizio MQ6 '23 generally has better picture quality, including color representation, but comes at a higher cost. For bright-room viewing, both are adequate, yet neither stands out. In terms of sound, both models offer basic performance; an external sound system is recommended for a more immersive experience. For those on a strict budget, the TCL S450F offers a fair overall experience at a lower price, but investing in the Vizio MQ6 '23 may yield a better viewing experience for various contents despite the additional cost.

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.
