The TCL S555 offers a slightly better overall viewing experience with more features and better sound quality, making it a strong contender if you desire a feature-rich TV and are willing to spend more. However, the Vizio MQ6 '23, while less expensive, still provides reasonable quality and performance that might suffice if you are looking for a TV to use in a typical domestic setting without specific high-end requirements. The Vizio may not match the TCL in terms of picture capabilities or audio, but it offers good value for a budget-friendly price. If the room where the TV will be used is particularly bright, neither TV is ideal, but the TCL may perform slightly better in these conditions. If cost is a primary concern and you're looking for a solid, no-frills television, the Vizio MQ6 '23 could be a more economical choice. Give Feedback

The TCL S555 (LCD) and Vizio MQ6 '23 (LCD) are both good for movies & TV, though the TCL S555 (LCD) is somewhat better.
The TCL S555 is praised for watching movies and cinematic TV due to its excellent contrast and good local dimming which enhance deep blacks and shadow detail, coupled with its strong black uniformity that minimizes distracting blooming around bright objects. The Vizio MQ6 '23 also serves well for the same content with its above-average contrast and effective local dimming, although its lower contrast compared to the TCL may affect the depth of blacks, it compensates slightly with better out-of-the-box colors and color volume that contribute to vibrant and varied hues.

The TCL S555 (LCD) is very good for cartoons & animation, while the Vizio MQ6 '23 (LCD) is good.
The TCL S555 excels in displaying cartoons and animation due to its 'very good' performance in the colors out of the box, ensuring an immediate and accurate color representation without need for calibration, and with its impressive color gamut that provides a wide spectrum of vibrant colors. In comparison, the Vizio MQ6 '23 also provides good color renderings right out of the box and a 'very good' color gamut, though it may not match the immediate vibrancy and color accuracy of the TCL S555.

The TCL S555 (LCD) is good for bright room, while the Vizio MQ6 '23 (LCD) is only fair.
The TCL S555 is better suited for bright rooms because it has very good SDR brightness and handles reflections poorly, meaning it can produce a brighter image that combats ambient light but struggles more with direct reflections. In contrast, the Vizio MQ6 '23 has good SDR brightness and handles reflections a bit better, indicating it can still offer decent brightness but can better mitigate reflections at the cost of some screen brightness.

The TCL S555 (LCD) and Vizio MQ6 '23 (LCD) are both only fair for sports.
The TCL S555 has a poor performance in handling reflections and a fair response time, which may affect the sports-watching experience in bright rooms and during fast-paced games. In contrast, the Vizio MQ6 '23 manages reflections better but also has a fair response time, making it somewhat better for viewing in well-lit environments but similarly limited during high-speed actions.

"It looks great out of the box and the picture quality it is rock-solid for the price. (...) What really makes this a decent gaming TV, though, is the very low input lag. (...) But if you want to save a little money, the TCL S555 strikes a great balance between cost and performance – the kind of performance that’s impressive enough to deliver some wow to your eyes. (...)"

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.
