The Sony X90K is generally more expensive but offers a better experience for gaming, with quick response times and lower input lag, making it well-suited for fast-paced action and competitive gaming environments. Additionally, with higher scores for motion processing, it ensures smoother scenes in sports and action movies. On the other hand, the TCL S555, while less expensive, might not be the best choice for gaming due to its lower scores in response time and input lag. However, it still provides good overall picture quality and better dark room performance for those who prefer to watch movies in a dimmed environment. In a bright room, both TVs are fairly comparable, although the Sony might have a slight edge in handling reflections. For sound quality, Sony's scores indicate a better audio experience, which could enhance your viewing pleasure without the need for external speakers. Ultimately, if your budget allows and gaming or fast motion content is your priority, Sony X90K could be the better choice. However, if you're looking to save money and want a TV with good overall picture quality for watching movies and TV shows, the TCL S555 would still make a solid choice. Give Feedback

The Sony X90K (LCD) is good for sports, while the TCL S555 (LCD) is only fair.
The Sony X90K has a higher motion processing capacity and handles reflections better, making it more suitable for sports in well-lit environments, whereas the TCL S555, despite good gray uniformity, falls short in motion processing and reflections, leading to a less optimal sports viewing experience. Viewing angles are limited on both, but more so on the TCL S555, which could affect the view from off-angles during sports gatherings.

The Sony X90K (LCD) is very good for gaming, while the TCL S555 (LCD) is only fair.
The Sony X90K has a higher refresh rate and better response time, making it very good for gaming, where fast-paced action is best displayed with minimal motion blur and quicker screen updates. In contrast, the TCL S555, while offering the best input lag which is great for reactive gaming, has a lower refresh rate and a good response time, making it fair for gaming as it may not handle fast motion as smoothly as the Sony X90K.

The Sony X90K (LCD) is very good for news, talk, & other TV, while the TCL S555 (LCD) is good.
The Sony X90K is preferred for its excellent upscaling of lower resolution content and very good SDR brightness, ensuring a clear picture in various lighting conditions, while the TCL S555, although good with colors out of the box and SDR brightness, offers a less effective upscaling of non-HD content, which might affect the clarity of news and talk shows on standard definition channels.

The Sony X90K (LCD) is very good for bright room, while the TCL S555 (LCD) is good.
The Sony X90K provides very good brightness in both SDR and HDR content along with superior reflection handling, making it more suitable for bright rooms than the TCL S555, which, while offering good brightness and reflection handling, falls slightly behind in performance in these very important aspects. Additionally, the X90K has better contrast, color volume, and color gamut, which are somewhat important factors that contribute to its advantage over the S555 in bright environments.

The TCL S555 (LCD) and Sony X90K (LCD) are both good for movies & TV.
The Sony X90K is well-suited for movies and cinematic TV because of its excellent local dimming and black uniformity, leading to deep blacks and strong contrast, but limited viewing angles can affect those watching from the side. The TCL S555 also performs well with movies, offering superb black uniformity which is essential for dark scenes, and a higher contrast ratio for vivid images, yet it may struggle with screen reflections more so than the Sony.

The TCL S555 (LCD) and Sony X90K (LCD) are both very good for cartoons & animation.
The Sony X90K presents colors fairly well out of the box and offers a good color gamut, which is essential for accurately depicting vivid and diverse colors typically found in cartoons and animations. The TCL S555 excels with colors right out of the box, making it immediately suitable for animated content without much adjustment, and it also supports a good color gamut for a vibrant display, though it may not match the overall color consistency of the Sony.

"As Sony’s next-to-flagship LCD TV, the X90K series delivers impressive performance for the price. The XR90K had fairly accurate out-of-box color. The TV’s multi-position stand lets you either set the screen flush with any stand its mounted on or elevate it to clear space for a soundbar. With the latter option, you get around 3 inches of clearance enough to accommodate most soundbars. The X90K’s excellent suite of gaming features ranks it up there with the best 120 Hz 4K TVs."

"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 Sony
Sony stands as a highly experienced and widely trusted TV manufacturer, earning a reputation that surpasses all others. A Japanese company, Sony has been making TVs for far longs than it has been making Playstation game consoles. Sony's high-end TVs are often regarded as the ultimate choice for videophiles, representing the epitome of quality, albeit at a premium price point. Renowned for their advanced and precise motion handling, as well as their cutting-edge local dimming algorithms, Sony consistently delivers unparalleled performance in these areas. They include Google TV software with all their TV sets, which grants access to the largest selection of apps available and they also include Bravia Core which is a movie streaming platform specifically for Sony TVs that offers higher picture quality by using more bandwidth.
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.
