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

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.
