The Samsung Q70A is a midrange-priced TV that typically costs significantly more than the TCL S450G, which is a budget option. If a better gaming experience is important to you, the Samsung Q70A offers higher performance and is a more suitable option. For general viewing of movies, sports, TV shows, and cartoons, the Q70A also presents a better picture quality, which justifies its higher price point. However, if you're on a tighter budget and primarily watch news or TV shows, the TCL S450G could suffice as it still delivers decent performance for these types of content. Both TVs may struggle in a brightly lit room, but the Q70A has a slightly better rating for such conditions. Neither option offers standout sound quality, so considering external speakers might be wise. If you're looking for a TV to double as a computer monitor, both allow for this usage; however, keep in mind that the Q70A supports a higher refresh rate which is favorable for smoother motion during gaming or high-action content.

The Samsung Q70A (LCD) is only fair for movies & TV, while the TCL S450G (LCD) is poor.
The Samsung Q70A provides a significantly higher contrast and slightly better black uniformity than the TCL S450G, which is particularly important for deep blacks and contrast in cinematic content. While both TVs are challenged by limited viewing angles, the Samsung Q70A's superior out-of-the-box colors and color volume offer a more vibrant and engaging movie-watching experience compared to the less impressive color performance of the TCL S450G.

The Samsung Q70A generally has better motion handling with a higher score than the TCL S450G, contributing to a smoother appearance when watching sports, and it has a faster response time which minimizes motion blur.

The Samsung Q70A (LCD) is good for gaming, while the TCL S450G (LCD) is poor.
The Samsung Q70A excels in gaming due to its very good response time and best input lag performance, making for a fluid and responsive gaming experience. On the other hand, the TCL S450G, with its poor response time and the same level of input lag, would result in a less optimal gaming experience, particularly noticeable in fast-paced games.

The Samsung Q70A (LCD) is very good for cartoons & animation, while the TCL S450G (LCD) is poor.
The Samsung Q70A excels in displaying cartoons and animation due to its 'Very Good' color out of the box and 'Good' color gamut, making vivid scenes look more colorful and true to life. In contrast, the TCL S450G performs poorly in the same regard because it has only a 'Fair' color out of the box and a 'Poor' color gamut, leading to colors that may appear more washed out and less vibrant.

The Samsung Q70A (LCD) is good for news, talk, & other TV, while the TCL S450G (LCD) is poor.
The Samsung Q70A delivers good upscaling of lower-resolution content like news or talk shows, ensuring clear images, and it comes with good out-of-the-box color accuracy, which means that colors will look natural without the need for calibration. On the other hand, the TCL S450G may not upscale lower-resolution content as clearly and has only fair out-of-the-box color accuracy, possibly requiring adjustments for optimal color reproduction during everyday viewing of news, TV programs, and talk shows.

About Samsung
Samsung, a South Korean electronics manufacturer, holds the title of being the largest global TV vendor in terms of units sold. They offer a diverse lineup of TV products that cater to various budget ranges. A notable achievement in recent years is the development of Quantum Dots, a technology that enhances color reproduction, resulting in richer and more vibrant hues. Samsung TVs are well-regarded for their high manufacturing quality and user-friendly software, making them an excellent choice for consumers seeking an intuitive viewing 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.
