The Samsung QN90A offers a premium experience with a much higher price, but excels in bright room performance, overall picture quality, and gaming. It features better reflection handling, motion processing, and higher brightness levels, which makes it ideal for well-lit rooms and varied content viewing, including sports and gaming. The TCL S555 is much more budget-friendly with lower picture quality and less impressive performance in bright rooms. However, it offers a good dark room viewing experience and is adequate for casual TV shows, movies, and animation. It's less suitable for sports and gaming due to lower motion processing capabilities. So if you value a high-quality picture and plan to use the TV in bright rooms or for gaming, the Samsung QN90A could be preferable, albeit at a higher cost. If you're looking for a more affordable option with decent performance for watching movies in a darker environment, the TCL S555 might satisfy your needs. Give Feedback

"It looks great out of the box and the picture quality it is rock-solid for the price. (...) What really makes this a decent gaming TV, though, is the very low input lag. (...) But if you want to save a little money, the TCL S555 strikes a great balance between cost and performance – the kind of performance that’s impressive enough to deliver some wow to your eyes. (...)"

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.
