From a stabilization point of view I prefer to have three points of contact between me and the camera - same principle as a tripod... So holding the camera to my eye (with the viewfinder) and tucking my elbows in tight has always provided a relatively stable platform for me. The longer the telephoto the greater the potential for camera shake holding the camera at a distance to the face with just two support points (as in a cell phone).
To me it's straight physics. But to each their own.
cheers, TREVOR
