The A4 is my take it easy, every day driver, but sometimes I hit the twisties pretty hard. The Primacy is the perfect tire for this use. Day in and day out, it's easy to forget about the tires because they are smooth and quiet, and they simply do their job. When I push it over the mountain roads, this tire isn't as good as the Pilot Sports I replaced, but it's much better as a daily driver with much less noise.
We don't get a lot of snow, but it's been pretty good on slick roads. The Quattro system is outstanding, but it's still the tire that does the work on these roads and the Primacy performs very well.
Given the way we use this car, the Primacy was the perfect pick.
