The Samsung QN90B, with its premium pricing, generally outperforms the Samsung CU8000, which is priced lower. If you prioritize overall picture quality and features such as gaming and viewing in bright rooms, the QN90B is a better option thanks to its higher performance in those areas. It has features such as full-array local dimming, higher brightness levels, and better dark room performance. On the other hand, if budget is a significant consideration and you're looking for a TV that is competent across various types of content without excelling in any particular aspect, the CU8000 is a cost-effective option. However, be aware that its performance in a bright room and for dark scenes is not as strong as the QN90B. Remember that the QN90B also has better sound quality, reflection handling, and a higher refresh rate which is ideal for fast-moving content, while the CU8000 could be more suited for casual viewing and standard daily use.

The Samsung QN90B (LCD) is good for sports, while the Samsung CU8000 (LCD) is only fair.
The Samsung QN90B outperforms the Samsung CU8000 when watching sports mainly because it has a faster response time and better motion processing, ensuring smoother action, while also offering superior handling of reflections and a wider viewing angle, which are crucial for a group sports viewing experience. The CU8000 falls short in these aspects, notably offering poorer reflections handling and a more limited viewing angle, which could affect the clarity and visibility for viewers not seated directly in front of the TV.

The Samsung QN90B (LCD) is excellent for news, talk, & other TV, while the Samsung CU8000 (LCD) is poor.
The Samsung QN90B excels in displaying news and TV programs because it has excellent SDR brightness and upscale quality, ensuring that lower resolution content looks clear and is easy to see even in well-lit rooms. Conversely, the Samsung CU8000 is considered poor for these types of content because it has lower SDR brightness and weaker upscaling abilities, which may lead to a more washed-out picture and lower clarity in bright conditions or with low-resolution broadcasts.

If all you’re planning on doing is watching cable TV, broadcast channels, and a fair share of streaming shows or movies, the QN90B is sure to impress.
