Basically none. Those boards are the same length as far as your feet
will feel, and any difference in how they ride will be due to other
factors (stiffness, flex profile, sidecut radius, damp or lively, etc).

If you're after a touch more control and looking to switch boards to do
it when you're already on a pretty short board, maybe you should put the
money into lessons.
