If you prefer watching movies and animations, the Hisense U6K might be appealing with better performance in dark rooms and better overall picture quality. On the other hand, the TCL S450F stands out with excellent black uniformity which is important for movie watching as well. For gaming, neither TV is ideal; the Hisense offers fair gaming performance while the TCL has poor gaming capabilities. When considering sports, both TVs offer fair performance. In bright rooms, both TVs perform fairly, but if you often watch TV in very bright conditions, you might need to look elsewhere. The Hisense has additional features such as Dolby Vision and Dolby Atmos support, which the TCL lacks, but it's at a higher price point. If budget is your primary concern, you could enjoy significant savings with the TCL without notable loss in quality for general content, but if you can invest more for a better viewing experience for movies and animation, the Hisense might be worth the extra cost.

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.
