When I stop it feels like an 80s GM car with no shocks. It bounces up and down when I stop. I have well over 80k on the clock. My 06 does not do this (tho is not perfect either) at over 60k mls.

Given that I got the 4.4 at 44k it is likely these are the ones that came from factory.

On my MB M-class the Bilstein HDs worked terrifically well (I changed after I got to Germany and the OEMs felt very unstable on the autobahn) but from reading here they are not all that suited to the X. So, I thought oem might be better.
