If you're looking for a more wallet-friendly option with good overall picture quality, the LG A1 is a solid choice and performs well in dark rooms. However, it's not as bright as the Sony A90J, making it less ideal for very sunny rooms. On the other hand, the Sony A90J, while more expensive, offers superior gaming performance, brightness, and sound—making it a better fit for mixed use in different lighting conditions and for gaming enthusiasts.

The Sony A90J (OLED) is excellent for sports, while the LG A1 (OLED) is very good.
The Sony A90J offers superior motion processing for watching sports, which results in clearer images during fast action, and it handles reflections better, making it more suitable for bright rooms than the LG A1. Both TVs have excellent response times and wide viewing angles, but the higher motion processing capability of the Sony A90J sets it apart, and its ability to handle reflections better also contributes to an improved sports-watching experience.

The Sony A90J (OLED) and LG A1 (OLED) are both very good for cartoons & animation, though the Sony A90J (OLED) is somewhat better.
The LG A1 provides "Good" colors out of the box with a "Very Good" color gamut, while the Sony A90J has "Very Good" colors right out of the box and also a "Good" color gamut, making the Sony A90J slightly better suited for viewers who prioritize color accuracy and richness in cartoons and animations. However, both TVs offer a high contrast, good gray uniformity, and adequate SDR brightness, important for animation viewing, but the A90J's higher SDR brightness could make it a better choice for watching in brighter rooms.

The Sony A90J (OLED) and LG A1 (OLED) are both very good for news, talk, & other TV, though the Sony A90J (OLED) is somewhat better.
The LG A1 excels at upscaling lower-resolution content, making it suitable for watching news and regular TV programs with clarity, but its SDR brightness is only fair, which can be a drawback in very bright rooms. In comparison, the Sony A90J also performs well with upscaling, and its SDR brightness is good, offering better performance in brighter environments, while also delivering very good colors out of the box, enhancing the overall picture quality without the need for much adjustment.

Although they have very similar scores, PerfectRec considers Sony A90J (OLED) to be excellent for movies & TV, while the LG A1 (OLED) is very good.
The LG A1 provides a very good movie and cinematic TV experience with perfect contrast, excellent local dimming, and outstanding black uniformity, enhancing dark scene portrayal, but its colors out of the box and gray uniformity are just good, with a slightly less impressive viewing angle. Meanwhile, the Sony A90J excels with similarly perfect contrast, excellent local dimming, and black uniformity, but stands out with very good color performance right out of the box and slightly better gray uniformity, though its viewing angles are comparable to those of the LG A1.

In fact, the Sony proves outstanding at handling on-screen motion of any and every kind. By the standards of television audio systems, the A90J is a notably punchy and genuinely dynamic performer."
