If you are on a budget and need an affordable option, the TCL S450R will save you money but offers only fair picture quality and is not ideal for gaming with its poor performance score. Its bright room performance is merely fair, so it might struggle in well-lit environments. On the other hand, the Samsung QN90A, while more expensive, delivers very good overall picture quality, excellent performance in bright rooms, very good gaming capabilities, and superb motion processing. This makes it a better choice for varied content, including sports, movies, gaming, and daytime viewing. However, its reflections handling is only fair, which might be an issue in very bright rooms. If you prioritize a higher quality viewing experience and better performance across different content types and environments, the Samsung QN90A could be worth the extra cost. 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.
