SX/SXi/SXi Pro 10-18 or 9-17....any difference?

Is there a noticable difference between a 9-17 prop and a 10-18? does it matter if its a "big hub?" thanks

i recently changed from a 12/17 to a 13/17 after damaging the 12/17. both are large hub props.
i did notice quite a difference on the bottom to midrange pickup.
