If you have a higher budget and desire superior overall picture quality, particularly for gaming and in bright rooms, the Samsung QN90A is an excellent choice. Its mini LED technology and good local dimming enhance contrast and brightness for a premium viewing experience. It's well-suited for different types of content, from movies and sports to general TV watching, and it performs exceptionally well with HDR content. On the other hand, the TCL S450F is a budget-friendly option that provides fair picture quality, but it may fall short in terms of gaming, motion processing, and brightness, especially in brightly lit environments. It offers basic performance suitable for less demanding viewing scenarios. If cost is a concern and your viewing requirements are modest, the TCL could serve as an economical option. However, for a more vibrant, responsive, and immersive experience, especially for varied and HDR content, the Samsung QN90A would be the better investment. 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.
