The Samsung CU8000 is a lower midrange priced TV that offers good value for its cost but is less capable when compared to the TCL R648, which commands a premium price. The TCL R648 has a higher refresh rate and better display features like MiniLED technology, which may result in a superior picture quality especially in dark room conditions. If you prioritize better overall performance and picture quality and are willing to invest more, the TCL R648 is the better option. However, if you want to save money and the differences in performance do not justify the additional cost for you, the Samsung CU8000 might be the preferable choice. Give Feedback

The TCL R648 (LCD) is very good for gaming, while the Samsung CU8000 (LCD) is poor.
The TCL R648 is better suited for gaming because it has a "very good" rating for response time, which ensures smooth motion with minimal blur, and good input lag performance that means faster reactions to user inputs, key for gaming. In contrast, the Samsung CU8000 has a "poor" response time, leading to more motion blur which can detract from the gaming experience, even though it has "very good" input lag performance.

The TCL R648 (LCD) is very good for cartoons & animation, while the Samsung CU8000 (LCD) is poor.
The Samsung CU8000 is rated lower for cartoons and animation mainly due to its 'Fair' performance in 'Colors Out of the Box', which affects the initial color accuracy and vibrancy that animations typically require. The TCL R648, on the other hand, is considered 'Excellent' in 'Colors Out of the Box' and has a similar 'Good' rating in 'Color Gamut', ensuring a wide range of colors and richer, more appealing visuals for animated content.

The TCL R648 (LCD) is good for news, talk, & other TV, while the Samsung CU8000 (LCD) is poor.
The Samsung CU8000's weaker performance in upscaling and SDR brightness makes it less suitable for watching news and TV programs, which typically aren't broadcast in high-definition, so upscaling is crucial to improve picture quality and brightness to adapt to various room conditions. On the other hand, the TCL R648 with its superior color performance right out of the box and higher SDR brightness ensures that regular content looks vibrant and clear even in brighter rooms, which explains its good performance for the same type of viewing.

The TCL R648 (LCD) and Samsung CU8000 (LCD) are both only fair for sports.
The Samsung CU8000 has a lower response time which is not ideal for sports, and less effective handling of reflections compared to the TCL R648, potentially affecting visibility in bright rooms. The TCL R648 has better motion processing, enhancing the viewing experience for fast-paced sports action, and it also manages reflections well but has a narrower viewing angle, similar to the Samsung CU8000, which might limit the viewing experience for larger groups.

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.
