The Amazon Omni Series is a more wallet-friendly choice but may not offer the best performance in bright rooms or for watching sports. It's less suitable for darker environments too. For general TV shows and casual viewing, it should suffice. The TCL R646, in comparison, is a stronger option for a variety of uses, including gaming, movies, and viewing in both dark and bright rooms. It has better sound quality and is more responsive, which could enhance the gaming and movie watching experience. However, both TVs have a similar price, so the TCL R646 could be considered better value for its overall performance. The TCL R646 also offers advanced features like high dynamic range (HDR) support with Dolby Vision and a higher refresh rate, which may make it a more future-proof choice. If these extra features align with your use case, and you're looking for improved picture quality and performance, the TCL R646 would be a worthwhile investment. Give Feedback

The TCL R646 (LCD) is very good for gaming, while the Amazon Omni Series (LCD) is poor.
The TCL R646 offers a very good gaming experience because it has very good response time and good input lag, which means reduced motion blur and quicker reaction to inputs, crucial for gaming. In contrast, the Amazon Omni Series has only fair response time and very good input lag, so while inputs are registered relatively quickly, the longer response time can make fast-moving images blurrier, impacting gameplay negatively.

The TCL R646 (LCD) is very good for cartoons & animation, while the Amazon Omni Series (LCD) is poor.
The Amazon Omni Series falls short for cartoon and animation viewing primarily due to its poor performance in colors out of the box and color gamut, which are critical for vibrant and varied color reproduction. In contrast, the TCL R646 is rated highly in the same areas, displaying a wide array of accurate colors that enhance the viewing experience for content full of colorful animations.

"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."

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.
