If you're looking for a more affordable option, the TCL S455 is less expensive than the Amazon Omni Series. It also slightly outperforms the Amazon Omni in overall picture quality, which could enhance your experience with regular TV shows and cartoons. For gaming, the TCL S455 offers a slight edge over the Amazon Omni. In bright rooms, the Amazon Omni has a better performance, which would make it preferable if you watch TV in well-lit spaces. However, for dark room viewing, both TVs are not ideal, with the Amazon having a slight lead. The sound quality of both TVs is comparable and neither has particularly great speakers, so if audio is important to you, you might want to consider an external sound system regardless of which TV you choose. Both TVs have similar support for HDMI connectivity and neither provides standout features for using them as a monitor. Neither TV supports advanced HDR formats like HDR10+ or Dolby Vision. In summary, the TCL S455 is a good choice for a tight budget, sports, and gaming, while the Amazon Omni may be preferable if you're willing to pay more for better performance in bright rooms.

Although they have very similar scores, PerfectRec considers TCL S455 (LCD) to be only fair for movies & TV, while the Amazon Omni Series (LCD) is poor.
The Amazon Omni Series TV struggles with contrast, lacks local dimming, and has mediocre black uniformity which dims its performance for movies and cinematic content, whereas the TCL S455, while having better black uniformity and some local dimming, still falls short due to limited contrast and color performance, affecting the overall viewing experience for darker scenes and vibrant content. Viewing angles and gray uniformity are also limited on both, impacting the color accuracy and consistency across the screen, which can be noticeable during movies that often display varied and nuanced shades.

Although they have very similar scores, PerfectRec considers TCL S455 (LCD) to be only fair for sports, while the Amazon Omni Series (LCD) is poor.
The Amazon Omni Series is considered poor for watching sports mainly due to its lack of motion processing capability and only fair response time, which can lead to blurrier images during fast-paced scenes. The TCL S455 fares somewhat better in sports viewing as it at least features some motion processing and also has a fair response time, reducing motion blur to a certain degree but still could handle motion better.

The TCL S455 (LCD) and Amazon Omni Series (LCD) are both poor for gaming.
The Amazon Omni Series and TCL S455 both have 60Hz refresh rates which might not be ideal for high-frame-rate gaming, and while the Amazon Omni Series has a 'fair' response time and 'very good' input lag, the TCL S455 also has 'fair' response time but better 'best' input lag, which may provide a marginally smoother gaming experience on the TCL model.

Although they have very similar scores, PerfectRec considers TCL S455 (LCD) to be only fair for cartoons & animation, while the Amazon Omni Series (LCD) is poor.
The Amazon Omni Series displays cartoons and animations poorly due to unimpressive color performance out of the box and a lackluster color gamut, which are crucial for vibrant and varied cartoon colors. The TCL S455, while still not exceptional, provides a somewhat better experience for the same content, with fair color accuracy from the start and a color volume that more effectively displays different shades and tones.

The TCL S455 (LCD) and Amazon Omni Series (LCD) are both only fair for news, talk, & other TV.
For watching news, talk shows, and other TV programs, both the Amazon Omni Series and TCL S455 perform similarly with fair upscaling and SDR brightness, vital for such content. However, the TCL S455 has a slight advantage with better colors out of the box, which means it can display a more vibrant picture without additional adjustments.

The Amazon Omni Series (LCD) and TCL S455 (LCD) are both only fair for bright room.
The Amazon Omni Series is fair for bright rooms because, while it has a good SDR brightness, which helps mitigate room brightness, its poor reflection handling limits visibility in well-lit environments. The TCL S455 also falls into the fair category as it has fair SDR brightness which is decent in bright rooms but its reflection handling is also fair, indicating some struggle with reflection control, which affects its performance in bright settings.

"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."

"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 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.
