If you're looking for an affordable option, the Samsung CU8000 is much less expensive and offers reasonable performance in many areas, including sports and cartoon content. However, it has limited brightness for HDR content and might not be the best for dark room viewing due to lower black uniformity. On the other hand, the Sony X90J is more expensive but provides significantly better picture quality across the board, including excellent gaming performance and dark room viewing experiences. It also offers better motion processing and overall color performance. Consider the Samsung CU8000 if budget is a priority, but if you're seeking high performance for a wide range of content and environments, the Sony X90J is a compelling choice despite its higher cost.

The Sony X90J (LCD) is good for sports, while the Samsung CU8000 (LCD) is only fair.
The Samsung CU8000 has a slower response time and less effective motion processing compared to the Sony X90J, which is more capable in these areas, making the Sony preferable for watching fast-moving sports. Additionally, the Sony X90J handles reflections better and maintains a wider viewing angle, ensuring clearer visibility from different seating positions, though both models could perform better in this aspect.

The Sony X90J (LCD) is very good for gaming, while the Samsung CU8000 (LCD) is poor.
The Sony X90J is considered very good for gaming because it has a very good response time, which is important for smooth motion, and good input lag, ensuring a quick reaction to user commands. On the other hand, the Samsung CU8000 has a poor response time, which can lead to motion blur in fast-paced games, but it does have very good input lag, which is beneficial for gaming responsiveness.

The Sony X90J (LCD) is very good for news, talk, & other TV, while the Samsung CU8000 (LCD) is poor.
The Samsung CU8000 struggles with upscaling and SDR brightness, giving a fair performance which can compromise the clarity of news and talk shows; furthermore, its color out of the box is only fair, indicating less vibrant and accurate colors initially.

The Sony X90J (LCD) is good for bright room, while the Samsung CU8000 (LCD) is poor.
The Sony X90J outperforms the Samsung CU8000 in bright rooms primarily because it has superior SDR and HDR brightness, helping it to maintain picture quality even in well-lit conditions; this is essential since both TVs struggle with reflections handling which is important when ambient light is present. Additionally, the higher contrast, color volume, and color gamut of the Sony X90J contribute to a more vibrant and detailed image in bright environments, whereas the Samsung CU8000's performance in these aspects is less impressive, making it less suitable for bright room viewing.
