The Samsung Q70A offers better overall picture quality and performs well for gaming with high responsiveness. It also has better performance in bright rooms compared to the TCL S455. On the other hand, the TCL S455 is more budget-friendly but won't perform as well in bright rooms or with gaming, and it offers slightly inferior picture quality. If you are willing to invest more for a better gaming experience and brighter room performance, the Samsung Q70A would be advisable. If you're looking to save money and can compromise on those aspects, the TCL S455 might be suitable. Both models have similar features like HDR support, but the Samsung has a 120Hz refresh rate which is better for gaming than the TCL's 60Hz. Give Feedback

The Samsung Q70A (LCD) and TCL S455 (LCD) are both only fair for sports, though the Samsung Q70A (LCD) is somewhat better.
The Samsung Q70A is characterized by a higher motion processing capability, which translates into smoother images during fast-paced sports scenes, and has better reflection handling, making it more suitable for brightly lit rooms compared to the TCL S455. However, both models have limitations when it comes to viewing angles, which means colors can appear washed out when viewed from the side, and they both offer fair gray uniformity, which could be problematic for displaying a uniform playing field during sports events.

The Samsung Q70A (LCD) is very good for cartoons & animation, while the TCL S455 (LCD) is only fair.
The Samsung Q70A delivers colors that appear vibrant and accurate straight out of the box, and it supports a wider range of colors, making cartoons and animations more vivid and immersive. In contrast, the TCL S455 has less accurate colors initially and a more limited color range, which can result in animations looking less lively and less true to their intended appearance.

The Samsung Q70A (LCD) is good for news, talk, & other TV, while the TCL S455 (LCD) is only fair.
The Samsung Q70A is more suitable for watching news and TV programs as it has a higher contrast and better SDR brightness, resulting in clearer images in various lighting conditions. On the other hand, the TCL S455 has lower contrast and SDR brightness, which may affect image clarity, especially in bright rooms, and can make it less ideal for daytime viewing of regular TV content.

The Samsung Q70A (LCD) is good for bright room, while the TCL S455 (LCD) is only fair.
The Samsung Q70A outperforms the TCL S455 in a bright room due to its superior SDR and HDR brightness, as well as better handling of reflections. However, the TCL S455, while rated lower for brightness and reflections, could offer more saturated colors with a somewhat better contrast, which may not fully compensate for its lower performance in well-lit environments.

The Samsung Q70A (LCD) and TCL S455 (LCD) are both only fair for movies & TV.
The Samsung Q70A is considered fair for movies and cinematic TV in part because while it has good contrast, it lacks local dimming and has only moderate viewing angles, which can limit deep black levels and consistent color when viewed from the side. The TCL S455 also offers fair performance for these uses due to its decent contrast and excellent black uniformity, but the absence of effective local dimming and its limitations in color performance out of the box, color volume, and viewing angles restrict its ability to deliver a more immersive cinematic experience.

"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 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.
