If you prefer a TV with better overall picture quality and gaming performance, the Hisense U6K is the better choice. It's typically more expensive, but it offers improved contrast, brightness, and gaming features compared to the TCL S450G. On the other hand, if you are looking for a more budget-friendly option and can sacrifice some picture quality, the TCL S450G could be suitable. It has a decent performance for watching news, talk shows, cartoons, and animations. However, its performance in a bright room and for dark room viewing isn't as strong as the Hisense U6K.

The Hisense U6K (LCD) is only fair for gaming, while the TCL S450G (LCD) is poor.
The Hisense U6K has a fair response time and very good input lag, making it suitable for casual gaming, whereas the TCL S450G, despite having the best input lag, is hindered by a poor response time, negatively affecting fast-paced gaming performance. Both TVs have a 60Hz refresh rate which is standard, but gaming experiences might still be smoother on the Hisense due to its better response time.

The Hisense U6K (LCD) is very good for cartoons & animation, while the TCL S450G (LCD) is poor.
The Hisense U6K is better for watching cartoons and animation due to its superior colors out of the box and color gamut, making the images more vibrant and accurate, while the TCL S450G's poor performance in these areas results in less appealing visuals.

The Hisense U6K (LCD) is good for news, talk, & other TV, while the TCL S450G (LCD) is poor.
The Hisense U6K is more suited for news, talk shows, and TV programs due to its superior upscaling that enhances lower resolution content and a "Good" ranking for colors out of the box, which means it displays accurate colors without the need for additional adjustments. Meanwhile, the TCL S450G delivers a "Poor" performance for watching such content, partly because its upscaling capability is not as effective and it ranks lower in colors out of the box, suggesting it may not reproduce colors as accurately as the Hisense U6K.

The Hisense U6K (LCD) is only fair for bright room, while the TCL S450G (LCD) is poor.
The Hisense U6K performs better in bright rooms primarily due to its higher SDR and HDR brightness levels, making it more suitable for bright environments than the TCL S450G, which has lower brightness capabilities. Additionally, both handle reflections fairly, but the superior brightness of the Hisense U6K gives it an edge over the TCL S450G in handling ambient light.

The TCL S450G (LCD) and Hisense U6K (LCD) are both only fair for sports.
Watching sports on the Hisense U6K could be less than ideal because its response time is poor and while motion processing is rated as good, viewing angles and handling of reflections are just fair, which may affect the viewing experience from different positions or in bright rooms. The TCL S450G shares similar traits with fair viewing angles and reflection handling and better response time, but its significant drawback is poor motion processing, which might lead to blurrier images during fast-moving sports. Both TVs are LCDs with VA panels, contributing to their limited viewing angles and reflection challenges. Gray uniformity is somewhat important and both are adequate in this aspect, which is beneficial when watching sports with uniform colors across the screen, such as a football field.

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.
