Choose the Samsung S90C if you prioritize top-notch gaming performance, deep blacks for watching movies in dark rooms, and wide viewing angles for group viewings. The TCL R648 may be preferred if you're looking for a brighter screen for well-lit rooms and powerful built-in speakers. However, the Samsung S90C also offers excellent color accuracy and higher-quality motion processing, making it a strong choice overall, especially for mixed content like movies, sports, and gaming, albeit typically at a higher price point. The TCL R648's advantage is its performance in bright rooms, which could be an important factor if you often watch TV with a lot of ambient light. 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.
