The Samsung QN90B may be the better option if you prioritize a top-notch viewing experience and are prepared to invest more. It excels in both bright and dark rooms and provides an excellent gaming experience, making it versatile for different types of content. On the other hand, the TCL S555 is far less expensive and still offers good performance, especially for movies and animated content. However, it may not handle reflections as well as the Samsung in very bright rooms, and its performance for sports and gaming is less stellar. Give Feedback

The Samsung QN90B (LCD) is good for sports, while the TCL S555 (LCD) is only fair.
The Samsung QN90B is better for watching sports due to its very good response time which reduces motion blur, and its excellent ability to handle reflections, maintaining a clear image even in bright rooms. Conversely, the TCL S555 has only a fair response time causing more motion blur during fast-paced sports and its poor reflection handling can result in a washed-out image when watching in well-lit environments.

The Samsung QN90B (LCD) is excellent for news, talk, & other TV, while the TCL S555 (LCD) is good.
The Samsung QN90B excels in upscaling lower-resolution content and achieving high brightness in SDR, making it outstanding for watching news and regular TV in various lighting conditions, and its out-of-the-box colors are rated as best. In contrast, the TCL S555, while it still provides very good upscaling and SDR brightness and very good color reproduction from the start, doesn’t perform at the same level, especially in terms of the effectiveness of its upscaling and SDR brightness.

The Samsung QN90B (LCD) is best in class for bright room, while the TCL S555 (LCD) is good.
The Samsung QN90B outperforms the TCL S555 in bright room viewing primarily due to its excellent scores in both SDR and HDR brightness and superior reflections handling, which together ensure a clear and bright picture even in well-lit environments. While the TCL S555 is also good in a bright room, with very good SDR brightness and fair reflections handling, it falls short of the Samsung QN90B's performance, particularly in HDR content, where the clarity and intensity of the picture are more crucial.

Although they have very similar scores, PerfectRec considers Samsung QN90B (LCD) to be very good for movies & TV, while the TCL S555 (LCD) is good.
The Samsung QN90B delivers a superior movie and cinematic TV experience due to its excellent local dimming and contrast, resulting in deep blacks and a vivid picture even in bright rooms, while its colors out of the box and color volume ensure a vibrant, true-to-life image. On the other hand, the TCL S555, while providing good contrast and decent black uniformity for its price, falls short in local dimming and viewing angles, which means it might not deliver the same level of depth and consistency across different viewing positions.

The Samsung QN90B (LCD) and TCL S555 (LCD) are both very good for cartoons & animation.

Meanwhile, the TCL S555 is very good in this regard due to its very good performance with colors out of the box and good color volume, although it may not match the Samsung's level of color vibrancy and depth.

"The QN90B delivers one of the brightest pictures we’ve ever seen, showcasing HDR content better than just about every LCD/LED TV on the market. If all you’re planning on doing is watching cable TV, broadcast channels, and a fair share of streaming shows or movies, the QN90B is sure to impress. All four of the QN90B’s HDMI 2.1 ports support 4K gaming at 120fps a centerpiece feature of the Xbox Series X and PlayStation 5."

"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.
