What are the differences between Audi's Quattro and All-Wheel Drive systems?

I'm considering buying an Audi, but I'm confused about the different types of drivetrain options. Can anyone explain the differences between Audi's Quattro and All-Wheel Drive systems and which one would be best for me? Thanks in advance!

Audi's Quattro system is a permanent all-wheel drive system that distributes power to all four wheels all the time, providing improved traction and stability in various driving conditions. On the other hand, Audi's All-Wheel Drive system is a part-time all-wheel drive system that primarily powers the front wheels and only distributes power to the rear wheels when needed. If you live in an area with inclement weather or frequently encounter slippery roads, Quattro may be a better option for you. Otherwise, All-Wheel Drive should suffice for daily driving.
