I wasn't aware shocks themselves could cause rattling. I was under the impression the connection points to the car were all essentially the same. Now CC plates and different coil over kits, those I've known to make noise.
I ran the bilsteins and the koni 3 way adjustables, as far as messing up the settings, pretty much anyone can navigate 3 settings...
I do kinda agree that at a point shocks for a street car are set it and forget it.
With that said, I ran the koni's on the stiffest setting for a couple years, then the medium setting, then the softest (where they stayed).
The softest setting unquestionably rode better than the bilsteins, i'd say they were closer to the stiffest.
So while adjustables may not get adjusted a lot after you find how you like it, it's nice to have a choice for a modest $50 difference in price.
Could you get whatever ride you prefer with a non adjustable? Likely, as long as you know what the set you are buying rides and handles like. Good luck with that.
Double adjustables is what I would avoid. Most people (including myself) would probably make things worse than better.
