As ws said, parabolic path would be a primary determinant but there are really way too many other factors to say that it would benefit a taller athlete. For instance, is the pit level (not with the runway but with itself) but uphill? Do both athletes land with the same extension (relative to themselves)? Any difference (and it really could go either way depending upon a number of variables), would be completely insignificant and uncondition.
