Choose the TCL R648 if you prefer a higher-quality picture, especially in darker rooms, better gaming performance, and superior sound with built-in Dolby Atmos. It's a premium option and costs more. Opt for the TCL S450G if you're on a budget and need a basic TV. It has a decent picture and supports HDR content but won't perform as well in bright rooms or for gaming. It also has a lower-quality speaker system. Give Feedback

The TCL R648 (LCD) is very good for gaming, while the TCL S450G (LCD) is poor.
The TCL R648 offers very good response time and good input lag, making it suitable for gaming as it can handle fast-moving images and react quickly to user input. In contrast, the TCL S450G, while having the best input lag which is great for gaming responsiveness, falls short with poor response time, resulting in more blur with fast-moving content, hence it is considered poor for gaming.

The TCL R648 (LCD) is very good for cartoons & animation, while the TCL S450G (LCD) is poor.
The TCL R648 excels in displaying cartoons and animations due to its excellent out-of-the-box colors and good color gamut, ensuring vibrant and accurate hues. In contrast, the TCL S450G performs poorly in the same content since it offers fair colors out of the box and a poor color gamut, resulting in less accurate and muted colors.

The TCL R648 (LCD) is good for news, talk, & other TV, while the TCL S450G (LCD) is poor.
The TCL R648 offers excellent SDR brightness and has a miniLED display which means it's more effective at lighting up the screen uniformly, enhancing the upscaling of lower resolution content and producing better contrast. On the other hand, the TCL S450G has poor SDR brightness and lacks local dimming, meaning its screen won't be as bright, and the contrast will be less pronounced, which detracts from the viewing experience, especially for news and talk shows where clear image quality is crucial.

The TCL R648 (LCD) and TCL S450G (LCD) are both only fair for sports.
The TCL R648 has a better response time and motion processing compared to the TCL S450G which makes it a better choice for watching sports where fast movements are common; however, the difference in their ability to handle reflections and offer wider viewing angles is marginal. Additionally, the TCL R648 has slightly better gray uniformity, which is less critical but still contributes to a more even display of sports fields and courts.

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.
