What is the difference between Audi A7 Quattro and S-Line?

I am looking to buy an Audi A7 and am wondering what the difference is between the Quattro and S-Line models. Can someone explain to me the main distinctions and which one might be better for my needs?

The main difference between the Audi A7 Quattro and S-Line models is the drivetrain. The Quattro has all-wheel drive, while the S-Line has front-wheel drive. This means the Quattro will provide better traction and handling in adverse weather conditions, while the S-Line may have a slightly smoother ride.
