Why is the Audi A8's Quattro all-wheel drive system considered superior?

I have heard great things about the Quattro all-wheel drive system in the Audi A8, but I am not sure what makes it stand out. Can someone explain its advantages over other all-wheel drive systems and how it enhances the overall driving experience?

The Quattro all-wheel drive system uses a self-locking center differential to distribute power between front and rear axles, providing better grip and control in various driving conditions. I have personally tested it in snowy and wet roads and can confidently say it outperforms others in terms of stability and handling.
