If you're looking for exceptional picture quality with deep blacks and vibrant colors, and don't mind spending more, the Samsung S90C OLED TV is an excellent option. It offers top-notch performance in dark rooms and is great for watching movies. However, it's not as bright as some LCD TVs, so it may not be as well-suited for very bright rooms. On the other hand, the TCL R646 is a midrange LCD TV that is significantly less expensive. It offers good performance in a variety of uses and has a brighter screen which is better for sunny rooms. If you're looking for value and a TV that performs well in bright conditions, the TCL R646 could meet your needs, but it won't deliver the same level of picture quality as the Samsung S90C, especially in dark room conditions.

The Samsung S90C (OLED) is excellent for movies & TV, while the TCL R646 (LCD) is good.
The Samsung S90C boasts perfect contrast, exceptional black uniformity, and effective local dimming, which enhances movie and cinematic TV experiences by delivering deeper blacks and preventing bloom around bright objects, crucial for dark room viewing. On the other hand, while the TCL R646 also offers good performance in these areas, its lower contrast, less efficient local dimming, and inferior black uniformity mean that it may not handle very dark scenes as effectively, especially in lit environments.

The Samsung S90C (OLED) is very good for sports, while the TCL R646 (LCD) is only fair.
The Samsung S90C (OLED) outperforms the TCL R646 (LCD) in sports viewing primarily due to its outstanding response time and motion processing, which minimizes blur in fast-moving scenes, as well as a superior handling of reflections and a wider viewing angle suitable for group watchings. While both TVs show some unevenness in gray uniformity which can be noticeable in large areas of similar color seen in sports fields, the OLED's strengths make it a better fit for dynamic sports content.

The Samsung S90C (OLED) is best in class for gaming, while the TCL R646 (LCD) is very good.
The Samsung S90C has the edge in gaming due to its superior response time and lower input lag which is crucial for fast-paced gaming, along with a higher refresh rate of 144Hz compared to the TCL R646's 120Hz, which makes the gameplay smoother. However, the TCL R646 still provides a very good gaming experience with its decent response time and input lag, and it's noteworthy that it also has solid sound quality which enhances the overall experience.

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.
