Based on the comparison, the Hisense U8K generally offers higher performance in most areas compared to the TCL S455. For those who prioritize picture quality, especially in brighter rooms or for watching movies and gaming, the Hisense U8K is the superior choice but comes at a higher price. It notably performs better in dark room settings, has a higher refresh rate and supports advanced audio formats like Dolby Atmos. On the other hand, if budget is a key concern and you're looking for a TV that's suitable for casual viewing in varied light conditions, the TCL S455 might be appealing despite its lower performance scores. It manages to perform decently at a significantly lower cost and has low input lag, which is still good for gaming. Give Feedback

The Hisense U8K (LCD) and TCL S455 (LCD) are both only fair for sports.
The Hisense U8K and TCL S455 both offer fair performance in key areas for watching sports: they have fair response times which is very important for fast-moving content, although their motion processing varies, with the Hisense having a lower score, meaning it may struggle more with fast-paced action. Both TVs may not be optimal in bright rooms or for wide seating due to their fair and somewhat important gray uniformity and reflections handling, and they have relatively narrow viewing angles.

"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 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.
