If you prioritize higher picture quality and gaming performance, the Hisense U6K is the better choice but it comes at a higher cost. This TV is well-suited for a dark room and has better reflection handling for brighter rooms. On the other hand, the TCL S446 is more budget-friendly and also performs decently in bright rooms due to good reflection handling, but it has lower overall picture quality which might not be ideal for movie enthusiasts or dark-room viewing.

The Hisense U6K (LCD) is good for movies & TV, while the TCL S446 (LCD) is poor.
The Hisense U6K is better for movies and cinematic TV due to its higher contrast ratio, effective local dimming, and superior black uniformity, which are important for producing deep blacks and detail in dark scenes. On the other hand, the TCL S446, while offering excellent colors out of the box and wider viewing angles, falls short in delivering the depth and detail in darker content due to its lower contrast ratio and lack of local dimming.

The Hisense U6K (LCD) is only fair for gaming, while the TCL S446 (LCD) is poor.
The Hisense U6K offers a fair response time and very good input lag, which are crucial for quick reflexes in gaming, whereas the TCL S446, with the same response time but only fair input lag, may lead to less smooth gameplay experiences. Despite both TVs having a 60Hz refresh rate, the better input lag on the Hisense U6K makes it more suitable for gaming.

The Hisense U6K (LCD) is very good for cartoons & animation, while the TCL S446 (LCD) is only fair.
The Hisense U6K is very good for watching cartoons and animation because it displays colors out of the box well and has a very good color gamut, ensuring vibrant and accurate colors. In contrast, the TCL S446, while it provides excellent colors out of the box, is held back by a poor color gamut, which limits the range of colors the TV can display, resulting in less vibrant animations.

The Hisense U6K (LCD) is good for news, talk, & other TV, while the TCL S446 (LCD) is only fair.
The Hisense U6K provides better upscaling and has superior out-of-the-box colors, offering a more refined viewing experience right away, which is particularly beneficial for regular programs like news and talk shows. In contrast, the TCL S446, while offering fair upscaling, tends to have poorer color reproduction out of the box and doesn't match the SDR brightness and contrast performance of the Hisense U6K, making it less ideal for such content.

The Hisense U6K (LCD) is only fair for bright room, while the TCL S446 (LCD) is poor.
The Hisense U6K performs better in a bright room than the TCL S446 because its SDR brightness is higher and it can better maintain contrast under bright conditions despite both TVs having a fair reflection handling capability. The TCL S446, on the other hand, has a lower SDR brightness, which along with its poor HDR brightness, makes it less suitable for viewing in well-lit environments.

The TCL S446 (LCD) and Hisense U6K (LCD) are both only fair for sports.
The Hisense U6K has a fair response time for sports, but struggles with wide viewing angles, reducing the clarity of the image from side seats, and it has mediocre motion processing, making fast-paced action less smooth. The TCL S446, while offering good reflection handling and wider viewing angles, also has just a fair response time and motion processing, limiting its ability to provide a crisp image during fast-moving sports games.

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.
