The TCL S334 is much less expensive and suitable for someone on a budget. It's good for gaming, news, and animation, but underperforms in bright rooms and doesn't offer high-definition experience as it lacks local dimming and HDR support. The Vizio Quantum Pro costs more but offers a superior picture quality, especially in bright rooms, and excels for movies and gaming. It has a higher resolution, supports various HDR formats, and has better sound capabilities, but it's not as cost-effective as the TCL model. Choose TCL S334 if saving money is a priority and you mostly play games or watch news and cartoons. If better picture quality and HDR are important and you're willing to pay more, the Vizio Quantum Pro is the better choice. Give Feedback

The Vizio Quantum Pro (LCD) is only fair for movies & TV, while the TCL S334 (LCD) is poor.
The TCL S334's poor performance in watching movies is due to its low contrast and lack of local dimming, which makes it less capable of displaying deep blacks and handling varied lighting, whereas the Vizio Quantum Pro, with better contrast and local dimming, offers a fair movie-watching experience, though both TVs face challenges with black uniformity impacting dark scene performance.

The Vizio Quantum Pro (LCD) is very good for gaming, while the TCL S334 (LCD) is poor.
The TCL S334 has a fair response time and poor input lag, which can result in slower reactions and more noticeable delay between user input and on-screen action during gaming.

The Vizio Quantum Pro (LCD) is good for cartoons & animation, while the TCL S334 (LCD) is poor.
The TCL S334 displays colors strongly fresh out of the box but suffers from a limited color gamut, making it less suitable for the vibrant colors typically found in cartoons and animations. Conversely, the Vizio Quantum Pro offers a vast color gamut, crucial for accurately presenting the full spectrum of colors intended by animators, making it a better choice for such content despite a lower initial color performance.

The Vizio Quantum Pro (LCD) and TCL S334 (LCD) are both only fair for sports.
The Vizio Quantum Pro and the TCL S334 are considered fair for watching sports mainly due to a fair reflection handling and reasonable motion processing, but they both struggle with limited viewing angles and lack standout response times, which can detract from the experience for fast-paced action. The Vizio Quantum Pro has a slightly better response time, which can be important for fast-moving sports, whereas the TCL S334 falls short in both response time and gray uniformity, meaning it may not present the playing field as uniformly as the Vizio.

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.
