The TCL R646 (LCD) is very good for gaming, while the Samsung AU8000 (LCD) is poor.
The Samsung AU8000 has a lower response time than the TCL R646, which can result in more motion blur during fast-paced gaming; however, it boasts better input lag performance, meaning it responds to your commands more quickly. The TCL R646 not only offers a very good response time which reduces motion blur, but also supports a higher refresh rate which is advantageous for smoother gameplay, although it does have a slightly higher input lag compared to the Samsung AU8000.

The TCL R646 (LCD) is very good for cartoons & animation, while the Samsung AU8000 (LCD) is only fair.
The TCL R646 displays cartoons and animation very well, partly because it has better color out of the box and a superior color gamut, ensuring vibrant and accurate colors, which are vital for animated content. Conversely, the Samsung AU8000 is considered fair for the same content because it can't match the TCL's level of color performance, which slightly affects the overall viewing experience for cartoons and animations.

The TCL R646 (LCD) and Samsung AU8000 (LCD) are both only fair for sports.
The Samsung AU8000 has better response time and viewing angles but reflects more light than the TCL R646, making the latter a better choice for rooms with a lot of light. However, the TCL R646 may show uneven colors on the screen during sports broadcasts due to its lower gray uniformity compared to the Samsung AU8000.

"To put it directly: you’d never see a mid-range 4K TV hitting this black levels half a decade ago. AU8000 plays the part of a higher-end TV thanks to its sleek design. If you’re upgrading to a smart TV for the first time, the software is a great way to dip your toes in the streaming water."

About Samsung
Samsung, a South Korean electronics manufacturer, holds the title of being the largest global TV vendor in terms of units sold. They offer a diverse lineup of TV products that cater to various budget ranges. A notable achievement in recent years is the development of Quantum Dots, a technology that enhances color reproduction, resulting in richer and more vibrant hues. Samsung TVs are well-regarded for their high manufacturing quality and user-friendly software, making them an excellent choice for consumers seeking an intuitive viewing experience.
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.
