The Hisense U6G is typically less expensive and performs well for watching movies, handling reflections, and has a good smart interface. However, the TCL R646, while usually costing more, has better performance in brightness, making it more suitable for well-lit rooms, and has a higher refresh rate which is ideal for gaming and watching sports. The TCL R646's superior color volume and gradient handling also make it a better fit for varied content viewing, though it may have a narrower viewing angle compared to the Hisense U6G. If budget is a key concern, the Hisense U6G offers good value, but for a superior viewing experience with brighter environments and fast-moving content, the TCL R646 could be a better choice.

The Hisense U6G (LCD) is very good for news, talk, & other TV, while the TCL R646 (LCD) is good.
The Hisense U6G delivers very good upscaling of lower-resolution content like cable TV, which is important when watching news or talk shows, and offers very good SDR brightness, making it suitable for most lighting conditions. The TCL R646 has excellent SDR brightness, enhancing visibility in bright rooms, and also good upscaling, though it is slightly less adept at handling lower-resolution content directly out of the box compared to Hisense U6G.

The TCL R646 (LCD) is very good for bright room, while the Hisense U6G (LCD) is good.
The TCL R646 outperforms the Hisense U6G in bright room settings due to its superior SDR and HDR brightness, combined with its excellent handling of reflections, which makes it very good for well-lit environments. While both have respectable color volume and gamut, contributing favorably to picture quality, these factors are less critical than brightness and reflection handling when it comes to viewing in bright rooms.

The TCL R646 (LCD) and Hisense U6G (LCD) are both good for movies & TV.
The Hisense U6G excels in black uniformity, which is crucial for deep blacks in dark scenes, enhancing movie and cinematic TV watching experiences, while its contrast and local dimming further improve picture quality, yet it has narrower viewing angles which might be limiting if you often watch from off-center. The TCL R646, on the other hand, offers better out-of-the-box colors and color volume, important for vibrant and realistic images, along with stronger contrast, but its black uniformity isn’t quite on par with the Hisense U6G, which can affect dark scene performance.

The TCL R646 (LCD) and Hisense U6G (LCD) are both only fair for sports.
The Hisense U6G has good response time, which helps with fast-moving sports content, but its fair reflection handling could be a problem in bright rooms and its poor viewing angles may limit the view for larger groups. In contrast, the TCL R646, while offering very good response time, also has very good performance against reflections and slightly worse but still limited viewing angles; it surpasses the Hisense U6G in gray uniformity, which is important for sports with large uniform colors like fields or courts.

The TCL R646 (LCD) and Hisense U6G (LCD) are both very good for cartoons & animation.
The Hisense U6G has colors that are well-represented right out of the box, with a strong color gamut, which makes cartoons and animation look vibrant and true to creators' intentions. On the other hand, the TCL R646 also offers good color reproduction and color gamut, plus it has higher SDR brightness which can make those same types of content pop even in brighter rooms.

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.
