The TCL R646 (LCD) and Hisense U6H (LCD) are both only fair for sports, though the TCL R646 (LCD) is somewhat better.
The Hisense U6H has poor performance in response time, which can affect the clarity of fast-moving sports scenes. On the other hand, the TCL R646 has very good response time ensuring sharper sports action, but it falls short in handling reflections which could affect viewing when the lights are on or in bright rooms, and has a narrower viewing angle which can impact those not sitting directly in front of the TV.

The Hisense U6H (LCD) is very good for news, talk, & other TV, while the TCL R646 (LCD) is good.
The Hisense U6H excels in upscaling content and has very good color accuracy straight out of the box, making it a strong choice for watching news, talk shows, and other TV programs. On the other hand, the TCL R646 offers better SDR brightness, which ensures a clearer picture in various lighting conditions, and it also has good color out of the box performance, though not as superior as the Hisense in this regard.

The TCL R646 (LCD) is very good for bright room, while the Hisense U6H (LCD) is good.
The TCL R646 outperforms the Hisense U6H in a bright room due to its excellent SDR and HDR brightness along with better handling of reflections, which are very important for viewing in bright environments. While both TVs have good color volume and gamut, which are somewhat important, the TCL R646's advantages in brightness and reflections handling give it a noticeable edge in bright room conditions.

The TCL R646 (LCD) and Hisense U6H (LCD) are both good for movies & TV.
The Hisense U6H delivers excellent colors out of the box and has good black uniformity, which makes for a rich movie-watching experience, but it may have a lower contrast ratio than the TCL R646. The TCL R646, on the other hand, offers a higher contrast ratio and better black uniformity, providing deep black levels that enhance cinematic scenes, especially in darker environments, but it might not present colors as accurately as the Hisense U6H right out of the box.

The Hisense U6H (LCD) and TCL R646 (LCD) are both very good for cartoons & animation.
The Hisense U6H and the TCL R646 are well-regarded for watching cartoons and animation because they both display vibrant colors straight out of the box and have a good color gamut, which ensures a wide range of colors. However, while both TVs perform similarly in color volume and contrast, which affect the richness and depth of the colors on screen, the Hisense U6H has a slight edge in SDR brightness, which is beneficial for viewing in well-lit rooms, whereas the TCL R646 excels in gray uniformity, providing more consistent shades across the screen.

Tom's guide
Matthew Murray | March 2023
"A budget TV that exceeds expectations. (...) For a TV that costs as little as this one does, its brightness and color are above-average (...) The U6H may not get quite as bright as its splashier siblings, but for its class, it fares pretty well. (...) As far as input lag, the U6H is an impressive performer. (...) Costing less than most of its direct competitors, and matching or bettering them in several key areas, it’s an irresistible value proposition. (...)"

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.
