If you prioritize having a more colorful and vivid display for movies and prefer spending a bit less, the TCL S555 is a good choice, but its reflections handling might be slightly worse, so it may not perform as well in bright rooms. On the other hand, the Hisense U6K is a solid choice for a bright room and generally offers good performance across the board, including gaming, but it tends to be somewhat more expensive. Both TVs have similar sound quality and the same number of HDMI ports. If gaming or using the TV as a monitor is important, the Hisense U6K has a marginally better gaming performance and can handle 4k at 120Hz, which the TCL cannot. Give Feedback

The TCL S555 (LCD) and Hisense U6K (LCD) are both only fair for sports.
The Hisense U6K and TCL S555's performance in watching sports is limited by their reflection handling, where the Hisense U6K is fair and the TCL S555 is poor, which might affect viewing in bright rooms, and by motion processing, where Hisense has a lower capability compared to TCL.

The TCL S555 (LCD) and Hisense U6K (LCD) are both only fair for gaming.
The Hisense U6K offers fair response time and very good input lag for gaming, whereas the TCL S555 provides good response time and the best input lag, making it slightly more responsive for fast-paced gaming. However, both TVs have a 60Hz refresh rate, meaning that neither is particularly well-suited for high-frame-rate gaming.

The TCL S555 (LCD) and Hisense U6K (LCD) are both very good for cartoons & animation.
The Hisense U6K and the TCL S555 are both LCD TVs with strong performance watching cartoons & animation due to their ability to display vibrant and accurate colors straight out of the box and their very good color gamuts; this means that both TVs will show cartoons with lively and varied colors, which is crucial for animated content. Although other factors like color volume, gray uniformity, contrast, and SDR brightness are also important and differ between the two models, the similarities in out-of-the-box color performance and color gamut make them both suitable for cartoons & animations.

Although they have very similar scores, PerfectRec considers TCL S555 (LCD) to be good for bright room, while the Hisense U6K (LCD) is only fair.
The TCL S555 is better for bright rooms due to its higher SDR brightness, which enhances visibility in well-lit settings, and despite poor reflection handling, it outshines the Hisense U6K, which has fair SDR brightness and reflection handling but falls short in very bright room conditions.

"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 Hisense
Hisense, a Chinese TV manufacturer, entered the US market in approximately 2011 and has since acquired TV divisions from various companies such as Toshiba, Sharp, Hitachi, and NEC. Currently ranking as the fourth largest vendor in terms of sales volume, Hisense aims to capture a wide range of TV budget segments. They offer exceptional value with TVs that often outperform their competitors at similar price points, making them a compelling choice for consumers. In the US, they use Google TV as their smart TV software which provides the largest app selection and a very modern user interface, however it is not as user friendly as the software from other vendors.
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.
