The Samsung QN90C is a premium-priced option that offers significantly better overall picture quality and performance, especially in brighter rooms due to its higher bright room score. It has superior gaming features, making it a great choice if gaming is important to you. It also has excellent sound quality with great speakers. On the other hand, the TCL S455 is more budget-friendly and will cost you much less. While it still offers good dark room performance, it won't match the Samsung in most viewing situations. The TCL has a simpler sound system without the high-end features of the Samsung. If you prefer saving money and don't need top-tier performance, the TCL S455 is a solid choice. However, if you're willing to invest more for better picture quality, gaming experience, and superior sound, the Samsung QN90C is advisable. Give Feedback

"A highly affordable but reliably kitted-out 4K Roku TV that, while far from perfect, still punches above its price and delivers a great user experience. If you want to soup up movie night for a bargain, the 4-Series won’t let you down. You may never need to plug in a set-top box or streaming device."

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.
