What is the mass opinion Koni -vs- Bilstein?

I am now running H&R springs and my KYB GR2 front
shocks aren�t dealing well with rebound.  I know the
Koni is a hydraulic shock and the Bils are gas &
that's about all I know.

What say you O' oracles of all Vanagon knowledge!

BTW, the H&R's are great... no more clearance issue
getting into my garage and I like the stiff ride, it
isn't as bad as I had expected at all  ;-)
