The Sony X90K generally offers better overall performance including picture quality, gaming experience, and ability to handle reflection in bright rooms. It costs more compared to the TCL S455, which offers a budget-friendly option with respectable performance for the price but doesn't handle bright rooms as well and offers lower picture quality overall. If you prioritize performance for a variety of content and have a bright viewing area, the Sony X90K might be a better fit, albeit at a higher cost. Conversely, if budget is a key concern and the environment isn't overly bright, the TCL S455 could suffice. Give Feedback

The Sony X90K (LCD) is good for movies & TV, while the TCL S455 (LCD) is only fair.
The Sony X90K is better for movies and cinematic TV due to its higher contrast, effective local dimming feature, and superior black uniformity, which are crucial for a good viewing experience in darker scenes. Meanwhile, the TCL S455, despite having decent black uniformity, falls short in contrast and local dimming, which leads to a less impressive picture quality for the same content.

The Sony X90K (LCD) is good for sports, while the TCL S455 (LCD) is only fair.
The Sony X90K is better for watching sports because it has superior motion processing and faster response time, leading to smoother action and less blur during fast-moving scenes. In contrast, the TCL S455 has weaker motion processing and slower response time, which can result in more motion blur and a less clear picture during dynamic sports events.

The Sony X90K (LCD) is very good for news, talk, & other TV, while the TCL S455 (LCD) is only fair.
The Sony X90K provides a very good upscaling quality and superior SDR brightness, which enhances the clarity and visibility of standard content like news and talk shows, compared to the fair upscaling and SDR brightness of the TCL S455 that may not render such content as bright or clear. Additionally, the Sony model has better performance in color reproduction and local dimming right out of the box, contributing to a more vibrant and consistent picture quality, unlike the TCL which fares lower in these somewhat important factors.

The Sony X90K (LCD) is very good for bright room, while the TCL S455 (LCD) is only fair.
The Sony X90K excels in a bright room because it has very good SDR and HDR brightness, which improves its visibility in well-lit environments, whereas the TCL S455, with its fair SDR brightness and fair reflections handling, is less capable of maintaining a clear picture under the same conditions. The superior brightness of the Sony X90K also enhances its contrast and color volume, contributing to a better overall viewing experience compared to the TCL S455.

"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."

"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 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.
