It'd be interesting (and easy?) to do some shock mount testing.... Setup stand and mics at specific gain in a quiet room, drop object from known height next to stand, record thump, compare to other mounts, etc.
Though that wouldn't cover the case where the sound pressure vibrates the stand more directly.
A lot depends on whether you're recording loud material with 20dB of gain, or classical guitar at 55dB..
In photography, carbon fibre tripods are far more effective at dampening vibrations than aluminum. Wood is also much better than aluminum. Additionaly, each system has resonant frequencies that may make them better or worse than others.
