I've owned a wholebunch, from a 1984 4000 quattro (neat stuff in the day) to a 2000 S4 to my present DD - a 2002 S6 avant.
All really good driver's cars, within the weakness of beign a) sedans and b) nose-heavy cars with too much weight in front of the axle.
I can speak best to the S6 avant. Ok, its nto entirely stock, but its still a very comfy ride. I do have ST coilovers, lowered, and -1.75 deg caber all around. But even on 16" street tires it is a very enjoyable car to rive on the track. I've done VIR, Pocono, many solo events.
Now, these are nto sports cars. The steering feel, the abiltiy to turn in fast, etc is vastly better in a boxster. Then agin, the boxster is also better in these regards than a 911, whcih is an Audi backwards, physics-wise (motor mostly behind rear axle, more weight).
I also drove a bunch of new S and RS audis on track at Montecello (MMC). Yea, they are a little soft, yea they have so little NVH that they are a bit numb, but they are very capable, predictable, and pretty darn fast. (note: i hated the RS-TT, buti digress).
But these cars are designed for different use cases, different target audiences, different expectations, etc. Just as a good track car is not a great road car, a great sports car is not a great luxury sedan.
BTW i sometiems have more fun pushng the "big pig" as i fondly call the S6 Wagon on track than a real track car. It makes me think ahead and be smooth. This says that it MUST communicate pretty darned well.
Dont knwo much abotu the recent, more mass-market cars.
