If you're on a tight budget and mainly watch news or cartoons, the TCL S355 could work for you, but it has poor performance across most content types and won't deliver a high-quality picture in dark or bright rooms. Conversely, if you're willing to invest more for a better overall and gaming viewing experience, the Samsung Q80B offers good picture quality and excels in bright rooms, with great capabilities for sports, gaming, and use as a monitor, including support for advanced features like HDR10+. However, it still has poor performance in very dark scenes and its speakers, despite being more powerful, might not satisfy audiophiles. Give Feedback

Tom's guide

Matthew Murray | February 2023
"For most people its picture, sound, and price make it a midrange TV worth considering. HDR brightness was generally exceptional. Its viewing angles are shockingly good, among the very best we’ve seen recently from any non-OLED TV. For gamers input lag isn’t too shabby."

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.
