If budget is a top priority and you're looking for a standard experience, the TCL S450R is a wallet-friendly pick, especially for dark room viewing due to its excellent black uniformity, and it's well-suited for casual gaming and everyday TV shows. However, the Vizio Quantum Pro offers superior picture quality, better for sports and HDR content with its higher brightness and color volume, and a smoother experience for gaming due to better motion handling. The Vizio's larger screen and better sound quality may enhance your movie-watching experience, but this comes at a higher cost. Choose the Vizio if you prioritize a more robust viewing experience and are willing to spend more, or opt for the TCL if you prefer to save money and can compromise on some advanced features.

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.
