Structurally or physically, I don't think there would be any advantage of one vs. the other.
I started noticing the difference when I was having trouble getting the spokes to fall into the right order so that the spokes on the right side of the hub would fall into the nipple holes toward the right side of the rim and vice-versa, especially with the old rims that have nipple holes offset, or staggered left, right, left, right, etc.
