The TCL S555 tends to be more expensive, but offers better overall picture quality and is especially good for watching movies and series. It also has superior sound, with great speaker quality. Conversely, the TCL Q6 is more budget-friendly and has very good picture quality for its price, making it a cost-effective choice for general TV viewing. In bright rooms, the TCL S555 performs slightly better, which could be important if you often watch TV during the day in well-lit spaces. For gaming, both TVs are capable, but the S555 has a slight edge in performance. If sound quality is a priority, the S555 has advantages, providing a better audio experience right out of the box. Ultimately, if you're on a budget and looking for good value, the TCL Q6 could be the right choice. However, if you're willing to invest more for improved picture quality, especially for movies and a better sound system, the TCL S555 would be the ideal choice. Give Feedback

The TCL S555 (LCD) is good for movies & TV, while the TCL Q6 (LCD) is poor.
The TCL S555 excels in watching movies and cinematic TV due to its superior contrast, effective local dimming, and better black uniformity, which contribute to deep blacks and good shadow detail crucial for dark scenes. In contrast, the TCL Q6 struggles with these aspects, as it has lower contrast, less effective local dimming, and worse black uniformity, leading to less impressive dark scene performance and a less immersive cinematic experience.

The TCL S555 (LCD) is only fair for gaming, while the TCL Q6 (LCD) is poor.
The TCL S555 is rated higher in response time than the TCL Q6 and both have the same top-tier input lag rating, which may give the S555 a slight edge in gaming performance. However, both TVs have a slower refresh rate, so while the S555 might handle motion slightly better due to its response time, neither will be as smooth for gaming as TVs with faster refresh rates.

The TCL S555 (LCD) is very good for cartoons & animation, while the TCL Q6 (LCD) is only fair.
The TCL S555 displays cartoons and animation better than the TCL Q6 due to its superior color performance right out of the box, making colors more vibrant and accurate for animated content. While both TVs have a good color gamut supporting a wide range of colors necessary for animation, the S555's higher contrast and better gray uniformity contribute to a more consistent and enjoyable viewing experience for colorful animated shows and movies.

The TCL S555 (LCD) and TCL Q6 (LCD) are both only fair for sports.
The TCL Q6 and TCL S555 both offer a fair experience for watching sports as they have similar poor reflection handling and response time, which are very important factors in sports viewing. However, the TCL Q6 has a slight edge in viewing angles, making it a marginally better choice for group watching in a well-lit room.

"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.
