If you often watch movies and prefer a clear picture in a dimly-lit room, the TCL S555 would be a better choice because it offers a better dark room performance. However, if you want a TV with a better smart platform for streaming and can afford to spend slightly more, the Amazon Omni Series may suit you better. If you plan to watch in a bright room, neither TV is particularly well-suited for that environment. Both TVs have a similar refresh rate, which is adequate for casual viewing but not ideal for high-end gaming experiences. Give Feedback

The TCL S555 (LCD) is good for movies & TV, while the Amazon Omni Series (LCD) is poor.

The TCL S555 (LCD) is only fair for gaming, while the Amazon Omni Series (LCD) is poor.
The Amazon Omni Series has a fair response time and very good input lag, which means it reacts relatively well to gaming inputs but may not transition between images as quickly as desired. The TCL S555, on the other hand, has a good response time and the best input lag, providing smoother transitions and more immediate reaction to gaming commands.

The TCL S555 (LCD) is very good for cartoons & animation, while the Amazon Omni Series (LCD) is poor.
The Amazon Omni Series struggles with watching cartoons & animation as it displays poor color out of the box and a poor color gamut, which are crucial for vivid and diverse colors. In comparison, the TCL S555 excels in the same content due to its very good performance in color out of the box and a good color gamut, ensuring a more vibrant and wider range of colors for animated visuals.

The TCL S555 (LCD) is good for news, talk, & other TV, while the Amazon Omni Series (LCD) is only fair.
The TCL S555 displays news and other TV programs better than the Amazon Omni Series partly because it has very good colors right out of the box and its SDR brightness is rated as very good, making it easier to see in most lighting conditions. Additionally, the TCL S555 benefits from better upscaling of lower-resolution content, which is important for watching various TV programs that are not in high definition.

The TCL S555 (LCD) is good for bright room, while the Amazon Omni Series (LCD) is only fair.
The TCL S555 is better suited for bright rooms because it has a higher SDR and HDR brightness, which helps maintain picture quality in well-lit environments. In contrast, though the Amazon Omni Series manages reflections fairly, its lower brightness makes it less ideal for bright rooms, and both struggle with reflections handling.

Although they have very similar scores, PerfectRec considers TCL S555 (LCD) to be only fair for sports, while the Amazon Omni Series (LCD) is poor.
The Amazon Omni Series has poorer performance when watching sports due mainly to its slower response time and less effective motion processing, which can make fast movements appear blurry. In contrast, the TCL S555 does a better job handling motion with a better response time and motion processing capabilities, but it still struggles with reflections, which can be distracting in bright rooms.

"If you want a competent budget screen with some handy features, the Amazon Omni TV delivers an experience that punches well above its price tag. You’ll also get the benefit of Fire TV’s new UI right out of the box. It’s clean and simple to understand, plus it puts content first. In the picture-quality department, the Amazon Omni is a surprising star among some of its dimmer, less colorful rivals."

"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 Amazon
Amazon, the largest online retailer in North America, has forged partnerships with TCL and Hisense to produce white-label TVs incorporating their Fire OS software. These Amazon-branded TVs typically compete in the low-end and mid-range segments, offering compelling price points. Leveraging their strong reputation, Amazon has swiftly built brand trust in the TV market despite being relatively new to it. To enhance their popularity, these TVs integrate features from the Amazon ecosystem, including Alexa, providing users with a seamless and interconnected TV 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.
