The TCL S450F is budget-friendly and offers good upscaling and viewing in dark rooms, but it's not the best option for bright rooms or gaming. Conversely, the Vizio Quantum Pro costs more but provides better sound quality, color volume, motion processing, and HDR performance. This makes it a solid choice for gaming and viewing in brighter rooms. If saving money is a priority and you mostly watch content in dark settings, the TCL might suit you. However, if you're looking for better overall performance in various settings and can invest more, the Vizio Quantum Pro would be the better choice. 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.
