It also depends on the shoulder width of your seat-neighbor. I think most people have wider shoulders than hips/butt, so squeezing into a narrower seat is more easily accomplished than leaning out to accommodate a wide-shouldered person in the middle seat (of which there are 33% more on the 3-4-3).
