Actually, they would be the exact opposite.
When I was buying dampers, I actually emailed KYB USA and got into a long back and forth with one of their reps. The short and long of it, the AGXs are designed with stock spring rates and height, so KYB reccomends no more than a 1" drop (which the Sportlines have a what...2.1"?) and no more than a 10% increase in rate. So the Sportlines have a better rate for the AGXs but the Pro Kits have a better ride height. The Sportlines are really just dress up springs, have a lower height, with fewer coils but are progressive. IIRC the Pro Kits are linear, but have a higher ride height and take better advantage of the camber curve of our oh so lovely MacPhearson strut type layout.
Just my $.02. Either way, for free, they are not a bad deal. I would not spend money on that setup however. Not when the Nismo setup I run is with in ~$100 retail.
