The Hisense U8K likely offers superior image quality and smart features, which could enhance your viewing experience, particularly with movies and gaming. If spending more doesn't concern you and you prefer a high-quality display and robust streaming capabilities, the Hisense U8K would be an excellent choice. On the other hand, the TCL S555 should be sufficient if you're looking for a budget-friendly option for casual watching, like TV shows or news, and it can still provide a satisfactory experience in various lighting conditions, including bright rooms. Keep in mind, though, that the lower price point might mean compromises in picture quality and smart functionality. Consider your viewing preferences and budget when making your decision.

The Hisense U8K (LCD) is very good for gaming, while the TCL S555 (LCD) is only fair.
The Hisense U8K is better for gaming than the TCL S555 because it has a faster response time and a higher refresh rate, which reduces motion blur and makes gaming more fluid, while the TCL S555, although having a slightly better input lag, doesn't match the Hisense's performance due to its lower refresh rate and slower response time.

The Hisense U8K excels in color reproduction with a very good color gamut and color volume, making the vivid colors in cartoons and animations pop, but it might not be as bright in standard dynamic range content.

The Hisense U8K (LCD) is very good for news, talk, & other TV, while the TCL S555 (LCD) is good.
The Hisense U8K is very good for watching news, talk shows, and TV programs due to its excellent upscaling and SDR brightness, which enhance the clarity of such content, and also has very good color accuracy out of the box, providing vibrant and true-to-life images. In comparison, the TCL S555 is good for these types of content with competent upscaling and SDR brightness, but falls short in local dimming and has poorer reflection handling, which can affect viewing experience in well-lit environments.

The Hisense U8K (LCD) is best in class for bright room, while the TCL S555 (LCD) is good.
The Hisense U8K outshines the TCL S555 in a bright room because it has higher SDR and HDR brightness and better handling of reflections, which are crucial in well-lit environments. While the TCL S555 has a high contrast ratio which benefits picture quality, its lower brightness and poor reflection handling make it less ideal than the Hisense U8K for bright room viewing.

The TCL S555 (LCD) and Hisense U8K (LCD) are both only fair for sports.
The Hisense U8K has a fair response time and very good handling of reflections, making it suitable for sports in rooms with some light but its motion processing is not the best. On the other hand, the TCL S555 offers good response time and motion processing, but performs poorly in handling reflections, which can be distracting during fast-paced games, especially in bright environments.

"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.
