What are the main differences between the Audi A7 Sportback and the Audi A7 S Line?

I am having trouble choosing between these two models of the Audi A7. Both have similar features, but there must be some significant differences that distinguish them. Can someone with experience owning or test driving these models provide some insights?

The main difference between the Audi A7 Sportback and the Audi A7 S Line is in the exterior design and performance. The Sportback has a sleek and streamlined look, while the S Line has a sportier and more aggressive appearance. In terms of performance, the Sportback offers a smoother and more comfortable driving experience, while the S Line has a more responsive and sporty handling.
