The Samsung S90C (OLED) is a premium option with significantly better overall picture quality, which is particularly great for gaming and watching movies in dark rooms. Its OLED screen provides better viewing angles and an absolute black that enhances contrast. The Samsung also has a better response time and lower input lag, making it ideal for fast-paced gaming. However, the TCL S555 (LCD) is more budget-friendly and still offers decent performance, especially for cartoons and animation. It's a solid choice for general use in bright rooms, with a respectable bright room performance, but it won't match the Samsung's picture quality or gaming features. So, if your budget allows and you value top-notched visual and gaming experiences, go for the Samsung S90C. But if you're looking for a more affordable option for everyday viewing, the TCL S555 could serve you well. 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.
