The TCL S455 is a budget-friendly option that provides a decent picture quality and performs well for movies, news, and animation. However, it may not be the best for watching in bright rooms or for gaming purposes. On the other hand, the Vizio Quantum Pro is typically much more expensive, offering better picture quality, higher performance for gaming, and a better experience in bright rooms. It also supports advanced formats like HDR10+ and Dolby Vision, and is equipped with voice commands, adding to its usability. If price is a primary concern and you mainly watch movies, news, or animation in darker settings, the TCL S455 may suffice. For a superior gaming experience, better brightness, and enhanced features, consider the Vizio Quantum Pro, if the higher cost is acceptable. Give Feedback

The Vizio Quantum Pro (LCD) is good for cartoons & animation, while the TCL S455 (LCD) is only fair.
The Vizio Quantum Pro is considered good for watching cartoons and animation as it has a very good color gamut, which means it can display a wide range of colors, and also exhibits very good color volume, allowing it to maintain those colors across different luminance levels. In contrast, the TCL S455 is considered fair in the same content due to its poor color gamut and fair color volume, resulting in a more limited color range and less consistent color reproduction at varying brightness levels.

The Vizio Quantum Pro (LCD) and TCL S455 (LCD) are both only fair for sports.
The TCL S455 has fair response times and motion processing, which may lead to some blur during fast sports scenes, but has poorer reflections handling and narrower viewing angles, making it less suitable for group viewing in brighter rooms. On the other hand, the Vizio Quantum Pro offers very good response times and better reflections handling, which makes it more favorable for watching sports in a variety of lighting conditions, although its motion processing is considered lower.

"A highly affordable but reliably kitted-out 4K Roku TV that, while far from perfect, still punches above its price and delivers a great user experience. If you want to soup up movie night for a bargain, the 4-Series won’t let you down. You may never need to plug in a set-top box or streaming device."

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.
