Bruv what are you talking about. There are plenty of people using performance vehicles as their daily. What's wrong with looking for a balance of performance plus comfort and wear? PS4S is known to be one of the most comfortable and long-lasting tyre. But the SC7 is much newer and is superior to the PS4S in both dry and wet. These data sets are from tests. Thus I'm asking for real world experience (or outside a track environment experience) in terms of dailying, how long does it last for them, etc. If you aren't a user of either you don't need to comment.
