The Samsung QN90C is a higher-end TV with a premium price tag, offering better overall picture quality, great performance in bright rooms, and superior gaming capabilities due to its high response time and low input lag. It's equipped with features like miniLED technology and has a wider viewing angle, which is beneficial for larger rooms or groups. On the other hand, the TCL S555 is more budget-friendly, providing decent overall picture with a focus on contrast and black uniformity, which is good for watching in dark environments. However, it has a 60Hz panel and poorer performance in terms of motion processing and gaming when compared to the Samsung. If you prioritize gaming, have a light-filled room, or want the latest features and can afford the higher price, the Samsung QN90C is recommended. But if you're looking for a more affordable option that still offers solid performance in darker rooms for casual viewing, the TCL S555 could meet 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.
