Only difference I see is that the first one is for Quattro systems and the second is for fwd.

HDs are commonly used as OE replacements. The Sports are the way to go if you plan on upgrading your wheels & suspension. The firmer valving allows them to cope with the added stresses of stiffer sprigs, etc.

I have tried both H&Rs w/ Bilsteins and Eibachs w/ Bilsteins . ..I prefer the latter.
