The brand doesn't matter ... all 'normal' shocks have a higher damping rate for rebound than compression!

Warren should Both new shocks match each other in speed of rebound. i.e. Both raise at the exact same speed.

With the 'de Carbon patent' high-pressure monotube gas shock designs , of which Bilstein are the most common example, it depends on how much gas pressure has bled off on the used shock. If there is no sign of oil leakage ... I would expect a worn-out shock to return faster on the return stroke than a brand-new replacement.
