If you prioritize picture quality, particularly deep blacks and high contrast, the LG B3 OLED is superior, especially in dimly lit environments. It's great for movies and has a sleek design but comes with a higher price tag. On the other hand, the Sony X90L LCD is more affordable and still delivers good quality for a variety of content, including sports and TV shows, and with its brighter screen, it's better suited for well-lit rooms. For gaming, both TVs have similar features; however, the LG B3 may offer a slightly better gaming experience due to its faster response time. Give Feedback

The LG B3 OLED excels in watching movies and cinematic TV with its perfect contrast, excellent black uniformity, and highly-effective local dimming that enhance dark scene details, whereas the Sony X90L LCD, while good for movies and cinematic TV, has lower contrast and black uniformity, as well as less effective local dimming, resulting in less impressive dark scene performance.

The LG B3 (OLED) and Sony X90L (LCD) are both very good for cartoons & animation.
The LG B3 OLED is highly regarded for watching cartoons and animation due to its very good performance right out of the box and its equally very good color gamut which contributes to vibrant and accurate colors. In contrast, while the Sony X90L LCD also has very good out-of-the-box color accuracy, it falls slightly short on color gamut, therefore it may not display as broad a range of colors as the OLED, which is especially noticeable in animated content that often uses a wide color palette.
