It's been my experience that bows tend to have less velocity deviation with heavier hunting weight arrows than with lighter target or 3D arrows. Some shorter limbed recurves might shoot much faster than a longer longbow of similar draw weight and quality with arrows of 8gpp, whereas the longbow might shoot faster with arrows of 15gpp (but probably not dramatically faster). Where you might (or might not) see more difference between bows is in other characteristics which are harder to measure, such as smoothness of draw, consistency between shots, reliability, and of course overall craftsmanship.
