How is the Audi A8's Quattro system superior to other all-wheel drive systems?

I am considering purchasing an Audi A8 and I have heard about their Quattro system. Can you explain how it works and why it is better than other all-wheel drive systems?

The Quattro system uses a center differential to distribute torque between the front and rear axles, providing a balance of power for optimal handling and traction. Unlike other systems that use reactive torque distribution, the Quattro system is proactive and continuously adjusts power distribution based on driving conditions.

With Quattro, power is sent to all four wheels consistently, rather than being redirected only when slip is detected like in other systems. This results in better acceleration and improved handling in corners.
