What's the difference between Audi's Quattro System and the S-Line Package?

I'm thinking of buying an Audi but I'm confused between the Quattro System and the S-Line Package. Can anyone explain the difference between the two and which one would be more beneficial for me?

The Audi Quattro System is the brand's signature all-wheel drive system, which offers enhanced traction and stability on slippery roads. The S-Line Package, on the other hand, is a cosmetic and performance upgrade that adds sportier features such as upgraded suspension, wheels, and styling elements.
