What are the main differences between the Audi A7 and the A8 model?

I am considering purchasing an Audi A7 but have also been looking at the A8 model. What are the key differences between these two models? Which one would you recommend and why?

The main difference between the Audi A7 and A8 is their size. The A7 is a sportier and more compact option, while the A8 is larger and offers a more luxurious experience.

Another notable difference is the price point. The A7 is typically more affordable than the A8 due to its smaller size and features.
