The Hisense U6K offers a better streaming experience with higher performance in picture quality and higher peak brightness, making it a smart choice if you often watch movies or enjoy gaming. However, it might not be the best option in a very bright room. On the other hand, the TCL S455 might save you some money and generally performs adequately, though its lower picture quality might be noticeable when watching sports or playing games. Both TVs have similar audio quality and their smart features differ, with the Hisense having voice command capabilities, which the TCL lacks. If you value a smoother user experience and can invest a bit more, the Hisense may be worth the additional cost. Give Feedback

The Hisense U6K (LCD) is good for movies & TV, while the TCL S455 (LCD) is only fair.
The Hisense U6K is preferred for watching movies and cinematic TV due to its superior contrast, effective local dimming, and better black uniformity, which are crucial for deep blacks and scene detail, especially in darker content. On the other hand, the TCL S455, while offering decent contrast, falls short with poorer local dimming and black uniformity, affecting its ability to deliver true-to-life images in similar content.

The Hisense U6K (LCD) is only fair for gaming, while the TCL S455 (LCD) is poor.
The Hisense U6K is considered fair for gaming because it has fair response time and very good input lag, which means it can handle fast-moving content with minimal delay. On the other hand, the TCL S455, while having the best input lag which is great for quick responses to user inputs, has only fair response time which can lead to less smooth motion in gaming.

The Hisense U6K (LCD) is very good for cartoons & animation, while the TCL S455 (LCD) is only fair.
The Hisense U6K provides a better experience watching cartoons and animation due to its very good colors straight out of the box, and a richer color gamut which ensures a wide range of colors are vividly displayed. In contrast, the TCL S455 offers a fair performance with less accurate colors initially and a poor color gamut which results in a less vibrant color representation for animated content.

The Hisense U6K (LCD) is good for news, talk, & other TV, while the TCL S455 (LCD) is only fair.
The Hisense U6K provides better upscaling and SDR brightness, which enhance the clarity and visibility of regular content, making it suitable for news and talk shows. In comparison, the TCL S455 has lower performance in these areas, which can affect detail and brightness in everyday viewing situations, but it does have a better color out of the box which may make content appear more vibrant initially.

The Hisense U6K (LCD) and TCL S455 (LCD) are both only fair for bright room, though the Hisense U6K (LCD) is somewhat better.
The Hisense U6K offers better SDR brightness than the TCL S455, which can be a crucial factor for viewing in bright rooms as it can make images appear clearer in such conditions. However, both the Hisense U6K and TCL S455 have fair reflections handling, implying that neither might be ideal when faced with direct light or reflected glare, as it can distract from the viewing experience.

The TCL S455 (LCD) and Hisense U6K (LCD) are both only fair for sports.
The Hisense U6K is fair for watching sports as it has an average response time which is critical for fast-paced action but struggles with motion processing, affecting clarity during fast movements. The TCL S455, also fair in this regard, has a similar response time and slightly better motion processing; however, both TVs have comparable difficulties with reflection handling and narrow viewing angles, which could affect the viewing experience from different positions in a bright room.

"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.
