The Samsung Q70A is typically much more expensive than the TCL S435 and provides a generally better experience for gaming, watching sports, and in bright rooms. It boasts better motion processing, a higher refresh rate which is beneficial for gaming, and slightly better speakers. The TCL S435, on the other hand, is a budget-friendly option and offers reasonable performance for the price, but its lower brightness and poorer handling of reflections make it less suitable for bright rooms or watching dynamic content like sports. Neither option excels in dark rooms, so if that's a priority, you may want to consider other models. Give Feedback

The Samsung Q70A (LCD) is only fair for sports, while the TCL S435 (LCD) is poor.
The Samsung Q70A is better suited for sports due to its very good response time which minimizes motion blur, and though it has poor reflection handling that might be troublesome in bright rooms, it nevertheless outperforms the TCL S435 which has a fair response time leading to more noticeable blur during fast action and equally poor reflection handling, making it less ideal for brightly-lit environments. Viewing angles are limited on both, but the Samsung's are somewhat better, which is important if you often watch games with a group, whereas the TCL will have more uniform color degradation when viewed from the side. Gray uniformity, which affects the perception of a uniform playing field, is comparable on both TVs, with the Samsung having just a slight edge.

The Samsung Q70A (LCD) is good for gaming, while the TCL S435 (LCD) is poor.
The Samsung Q70A provides a very good response time and the best input lag performance, making it ideal for gaming that requires quick screen refresh and minimal delay in registering inputs. In contrast, the TCL S435 offers only fair response time and poor input lag, which can result in noticeable delay and less fluid motion during gaming.

The Samsung Q70A (LCD) is very good for cartoons & animation, while the TCL S435 (LCD) is good.
The Samsung Q70A is considered very good for watching cartoons & animation due to its very good color performance right out of the box and good color gamut, which ensures vibrant and consistent colors across different content. In contrast, the TCL S435 is good for cartoons & animation and provides excellent colors out of the box, but with a fair color gamut, which might result in less accurate color reproduction.

The Samsung Q70A (LCD) is good for news, talk, & other TV, while the TCL S435 (LCD) is poor.
The Samsung Q70A is better suited for watching news, talk shows, and other TV programs than the TCL S435 due to its very good upscaling and SDR brightness, which enhance picture quality on non-HD content often found in such programs. Additionally, the Q70A has better colors out of the box, a good color gamut, and good color volume, all contributing to a more vibrant and accurate display, whereas the S435, despite having excellent colors out of the box, falls short in its fair color gamut and color volume, ultimately offering a less impressive viewing experience.

The Samsung Q70A (LCD) is good for bright room, while the TCL S435 (LCD) is poor.
The Samsung Q70A is superior for viewing in bright rooms as it has a higher SDR and HDR brightness and is better at handling reflections, making it more suitable for such environments. On the other hand, the TCL S435 struggles in bright rooms due to its lower SDR and HDR brightness and poor reflection handling, despite its decent contrast and color volume performance.

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.
