The difference is that if you have a target resistance value, the thickness of the resulting cable of either material is of little practical importance. With vibration absorption, space may very well be an issue in some applications (eg inside a case), where a thinner material would be beneficial. Unfortunately I do not recall what differences in thickness we're talking about here, percentage wise.
I found some years ago that something like a cuddly toy sitting on a rubbery-backed carpet tile removed audible casework hum from an amp. Looked Ok, as well.
...actually, at present one amp has a cuddly-top cat with a cuddly-top snoopy riding it as a mechanical hum damper. Other types of cuddly toy are available. We do also have a number of elephants as my better half like them.
