If you prioritize overall picture quality and can invest more, the Samsung QN90C would be a better choice as it offers superior performance, especially in bright rooms. However, if budget is a concern and you are looking for a quality TV at a midrange price, the Samsung Q70A is a good option, though it won't perform as well in bright environments or provide as high a level of picture quality. For gamers, both models have low input lag, but the QN90C is slightly better. The QN90C also has great speakers, while the Q70A does not. Give Feedback

The Samsung QN90C (LCD) is very good for movies & TV, while the Samsung Q70A (LCD) is only fair.
The Samsung QN90C displays movies and cinematic TV content very well owing to its excellent local dimming feature, which enhances contrast and black uniformity, while its superior color volume and gray uniformity also contribute to a richer viewing experience. In contrast, the Samsung Q70A is fair for movies and cinematic TV because it lacks local dimming, has lower gray uniformity and color volume, and despite a higher contrast ratio, it falls short in maintaining consistent picture quality compared to the QN90C.

The Samsung QN90C (LCD) is very good for news, talk, & other TV, while the Samsung Q70A (LCD) is good.
The Samsung Q70A provides a very good upscaling and SDR brightness which are essential for clear image quality in news and talk shows, while the Samsung QN90C excels in these areas with the best SDR brightness and slightly better upscaling which enhances its performance for the same content. Additionally, the better contrast, color reproduction right out of the box, and local dimming on the QN90C contribute to a more vibrant and detailed viewing experience, despite being a newer and likely more expensive model.

Although they have very similar scores, PerfectRec considers Samsung QN90C (LCD) to be good for sports, while the Samsung Q70A (LCD) is only fair.
The Samsung Q70A has a fair performance for watching sports due to its poorer reflections handling and more limited viewing angles, which could reduce the viewing experience in a bright room with a wide seating arrangement. In contrast, the Samsung QN90C offers a good experience for sports watching thanks to its excellent reflection handling and better viewing angles, ensuring clearer visibility even in well-lit spaces and across a broader range of seating positions.

Although they have very similar scores, PerfectRec considers Samsung QN90C (LCD) to be very good for gaming, while the Samsung Q70A (LCD) is good.
The Samsung Q70A boasts an outstanding response time which is crucial for gaming as it minimizes motion blur during fast-moving scenes, but its input lag is not as good as the Samsung QN90C, which has both excellent response time and exceptional input lag, ensuring a very responsive gaming experience, especially important for fast-paced competitive gaming. While both TVs are good for gaming, the QN90C offers a slight edge for gamers seeking the most immediate feedback from their on-screen actions.
