If you prefer a TV that overall performs better in various content like movies, is more suitable for gaming, and handles well in dark room conditions, the Vizio MQ6 '23 may be the better option. This model also includes voice commands for easier control. However, this comes at a higher cost compared to the TCL S455. On the other hand, if you're looking for a more budget-friendly option, the TCL S455 is less expensive but won't perform as well in a dark room or with gaming, and lacks voice command functionality.

The Vizio MQ6 '23 (LCD) is good for cartoons & animation, while the TCL S455 (LCD) is only fair.
The Vizio MQ6 '23 is better for watching cartoons & animation than the TCL S455 because it delivers more accurate colors out of the box and has a wider color gamut, which is crucial for vivid and varied cartoon imagery. While both TVs have similar gray uniformity and SDR brightness, impacting their ability to display consistent colors across the screen and how well they perform in different lighting conditions, the superior out-of-the-box color accuracy and gamut of the Vizio provide a better viewing experience for content with rich and diverse color palettes.

The Vizio MQ6 '23 (LCD) and TCL S455 (LCD) are both only fair for sports.
The TCL S455 has a fair response time which is crucial for watching fast-paced sports, but its poor handling of reflections and narrow viewing angle could be problematic in bright rooms or for groups. Conversely, the Vizio MQ6 '23, while sharing a fair response time and similar challenges with reflections, has a slightly worse viewing angle and gray uniformity, which may slightly affect the viewing experience when watching sports across a wide seating area.

The Vizio MQ6 '23 (LCD) and TCL S455 (LCD) are both only fair for bright room.
The TCL S455 and Vizio MQ6 '23 are both LCD TVs that have fair performance in bright rooms primarily because they offer fair reflection handling, limiting the impact of ambient light on-screen visibility. However, they have different brightness capabilities with the TCL S455 being fair in both SDR and HDR brightness, whereas the Vizio MQ6 '23 has good SDR brightness but poor HDR brightness, and this, along with their acceptable contrast, color volume, and color gamut, makes them suitable but not exceptional for well-lit environments.

"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.
