It's always seemed to me that the shorter scale of Gibson and similar length necks inherently lend themselves to looser string tensions, most noticeable on the E and A strings. Aside from the difference in sound which is totally a taste-preference thing, the difference in tension translates to a difference in action, and thus playability. That "bassy" sound of a shorter scale for my taste gets really diluted with shorter strings, sometimes compensated for by greater diameter strings. But then we get into the action questions of round wound vs. flat-wound, and the discussion starts anew. Personal styles range all over the map, thankfully, and the kind of music a bass is playing will further influence choice/sound/action/style.
