I believe more vibration in an SLR comes from the mirror lockup than
from the shutter.

But it's a matter of physics in any case (inertia, specifically; this is
a case of action-reaction).  Whichever camera has the lighter shutter,
all else being equal, will suffer less shake, since there will be less
reaction (motion transferred to the camera body) to the body's action of
moving the shutter.
