Choose the Samsung S90C if picture quality, especially in gaming and watching movies, is a priority and you're willing to spend more. It offers superior overall picture, exceptional contrast, and excels in both dark and bright rooms, alongside excellent performance with wide viewing angles. Go for the TCL S455 if budget is a concern and your viewing needs are more basic. While it's more affordable, it offers lower picture quality, less impressive performance in dark environments, and limited brightness capabilities which can affect viewing in very bright settings. The Samsung is an OLED with wider color gamut and high refresh rate, whereas the TCL is an LCD with fewer advanced features. Both have the same screen size and number of HDMI ports, but the Samsung has additional features like voice commands and supports more HDR formats. Give Feedback

The Samsung S90C (OLED) is very good for sports, while the TCL S455 (LCD) is only fair.

"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.
