If you're looking for a more budget-friendly option, the Samsung CU7000 might suit you since it is significantly less expensive. However, it has lower picture quality and brightness levels, making it less ideal for very bright rooms and darker settings where it won't perform as well. On the other hand, if you prefer higher picture quality and are willing to pay more, the TCL R646 could be a better option. It offers better performance in bright rooms and delivers better contrast and high dynamic range (HDR) support. The TCL R646 also provides a better experience for movies and series with higher quality sound, but may not be as impressive for regular news, talk shows, or as a computer monitor as the Samsung model. Keep in mind, both TVs have limitations with viewing angles, and neither has great speakers. Give Feedback

The TCL R646 (LCD) is very good for gaming, while the Samsung CU7000 (LCD) is only fair.
The TCL R646 offers a very good gaming experience due to its higher response time and input lag performance, important for a smooth and responsive gameplay, while the Samsung CU7000, despite solid input lag, is held back by fair response time, which might not be as suitable for fast-paced gaming actions.

The TCL R646 (LCD) is very good for cartoons & animation, while the Samsung CU7000 (LCD) is poor.
The TCL R646 displays cartoons and animation very well due to its good colors out of the box and good color gamut, which are essential for the vibrant and varied colors typically found in such content. In contrast, the Samsung CU7000 performs poorly with cartoons and animation because its colors out of the box and color gamut are both rated as poor, leading to less accurate and less vivid color representation.

The TCL R646 (LCD) is very good for bright room, while the Samsung CU7000 (LCD) is poor.
The Samsung CU7000 performs poorly in bright rooms mainly because it has lower SDR and HDR brightness and struggles more with reflections compared to the TCL R646, which exhibits higher brightness levels and better handling of reflections, making it very good for viewing in well-lit environments. Additionally, while contrast along with color volume and gamut are less critical, the TCL R646 still holds an advantage in these areas, contributing to its overall superior performance in bright rooms compared to the Samsung CU7000.

The Samsung CU7000 (LCD) and TCL R646 (LCD) are both only fair for sports.
The Samsung CU7000 and TCL R646 both have fair response times, suitable for watching sports, but they differ in motion processing where the TCL R646 is less capable, affecting the smoothness of fast-moving content. Both TVs handle reflections decently, but the Samsung CU7000 might struggle more in bright rooms; for sports viewers partly positioned off to the side, neither TV offers wide viewing angles, which could compromise the picture quality from certain seats.

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.
