The Sony X90J (LCD) is very good for cartoons & animation, while the LG NANO90 (LCD) is poor.
The LG NANO90 struggles with cartoon and animation viewing due to its poor out-of-the-box colors and a fair color gamut, which results in less accurate and vibrant colors. In contrast, the Sony X90J is very good for such content, boasting excellent color accuracy straight out of the box and a good color gamut, enhancing the vibrancy and authenticity of cartoon images.

The Sony X90J (LCD) is very good for news, talk, & other TV, while the LG NANO90 (LCD) is only fair.
The Sony X90J is considered very good for watching news and TV programs due to its superior upscaling capabilities and its effective local dimming which boosts the contrast, resulting in sharper details and deeper blacks. In contrast, the LG NANO90, while fair in this regard, doesn't match the Sony's performance due to its poorer upscaling and local dimming ability which affects overall picture quality for standard dynamic range (SDR) content like news and talk shows.

The Sony X90J (LCD) is good for bright room, while the LG NANO90 (LCD) is only fair.
The Sony X90J performs better in bright rooms mainly due to its superior SDR brightness, which helps maintain picture quality even in well-lit environments, whereas the LG NANO90 has lower SDR brightness, which can result in a more washed-out image in similar conditions. Additionally, the Sony X90J doesn't handle reflections as effectively as the LG NANO90, but its higher brightness compensates for this shortcoming, making it the better option for bright rooms overall.

Although they have very similar scores, PerfectRec considers Sony X90J (LCD) to be good for sports, while the LG NANO90 (LCD) is only fair.
The Sony X90J is better for sports because it has superior motion processing which ensures smoother action, and it has good reflection handling, which reduces distractions from light sources in the room. On the other hand, the LG NANO90 offers wider viewing angles which can be advantageous in a group setting, but it has lower motion processing capabilities which can result in less fluid movement during fast-paced games.
