I own the D4 A8 since 2014 and in many of my ski trips I've rented the S W222.
I can say that I noticed a bit more cost cutting in S class, especially door panels and trunk area. Some switch gear in the S class like the sun visor are carried over from a 2004 CLK, my AMG GT has the same old things, which is silly.
The ride obviously is more comfortable in the S class, however less dynamic and too boaty for my liking. My A8 feels like a smaller car.
I also drove the 7 Series for a couple days and I really liked the drive train, very responsive and dynamic, couldn't notice that it's a diesel engine.
I even considered buying it but I can't justify the 60k euro over my current car, it just doesn't feel like a major departure, maybe because of the black interior.
The new A8 is a well engineered car but interior is too spaceship.
Seems like you'd like the Panamera, especially in regards to a dynamic ride.
