If you prioritize gaming and watching sports, the Sony A90K could be a better choice with its higher refresh rate and performance in these areas. However, the LG A1 has almost equivalent picture quality and could save you some money. The Sony A90K is better suited for rooms where glare is an issue, but it doesn't perform as well in bright rooms compared to in darker environments. For standard viewing, such as watching movies and TV shows, both TVs offer very good experiences. If you are considering using the TV as a monitor, the Sony would be more suitable due to its better suitability for this use. Keep in mind, the LG A1's sound power is lower, so you may need to invest in a sound system if audio performance is important to you. Give Feedback
