[s-cars] boge vs bilstein shock advice

[Scot Anderson, DC]

Tried search, but no luck.  Anyone have advice/experience with Boge Turbo Gas shocks.  According to Blauparts.com, Boge shocks increase ride firmness by 15% and have no reference as for the Bilsteins.  Blauparts sells them for $389 vs the Bilsteins for $479 - not a huge price diff (this is the cheapest place I have found for the Bilsteins).  It seems everyone has Bilsteins on their urS - I assume because they are a better product???
