The TCL R646 (LCD) is good for movies & TV, while the Samsung Q70A (LCD) is only fair.
The TCL R646 displays movies and cinematic TV shows better, partly due to its superior local dimming feature, enhancing contrast and black uniformity, both key for dark room viewing. While the Samsung Q70A excels in colors out of the box, which benefits color-critical content, its lack of local dimming can affect deep black levels, crucial for a cinematic experience.

The TCL R646 (LCD) is very good for bright room, while the Samsung Q70A (LCD) is good.
The TCL R646 outshines the Samsung Q70A in bright rooms mainly because it has a higher SDR brightness and handles reflections better, which are both very important for clear viewing in well-lit environments. Although both TVs perform well in terms of contrast and color, which are somewhat important for picture quality, the TCL's superior reflection handling and greater brightness give it an edge in such settings.

The Samsung Q70A (LCD) and TCL R646 (LCD) are both only fair for sports.
The Samsung Q70A and the TCL R646 both offer very good response times which is crucial for sports viewing to ensure smooth motion, but their reflections handling greatly differs; the Samsung Q70A struggles with reducing reflections, possibly affecting the viewing experience in bright rooms, whereas the TCL R646 is very good at minimizing reflections, making it a better choice for well-lit spaces. Viewing angles are limited for both, which may require central seating for sports gatherings, and while both show fair gray uniformity, it is somewhat better on the TCL R646, enhancing the experience when watching sports that often display large uniform colors like a football field.

Although they have very similar scores, PerfectRec considers TCL R646 (LCD) to be very good for gaming, while the Samsung Q70A (LCD) is good.
The TCL R646 is noted to have a better input lag performance than the Samsung Q70A, which makes it more favorable for gaming where fast reflexes and timely reactions are essential. Both the Samsung Q70A and the TCL R646 have very good response times and refresh rates, enhancing clarity and smoothness in fast-moving games, but the TCL's superior input lag may offer a slightly more responsive gaming experience.

The Samsung Q70A (LCD) and TCL R646 (LCD) are both good for news, talk, & other TV.
The Samsung Q70A is well-suited for news, talk shows, and regular programming because it has very good upscaling capabilities and a high SDR brightness, which ensures clear images even in well-lit rooms. The TCL R646, while also good at upscaling, excels mainly due to its excellent SDR brightness and superior local dimming feature which enhances contrast, making it a strong option for those types of content as well.

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.
