Sachs shocks on an A-body?

On a M-B owners forum I attend, owners discuss Sachs and Bilstein as best. Bilstein is more expensive, while Sachs is "good enough" for most. I might have Sachs on my 1985 300D, but don't care enough to verify. I suspect half the opinions are by people like audiophiles of old who could supposedly hear things from quality turntables and amplifiers which us mere mortals couldn't, yet they would never submit to a blind with and without hearing test.
