Given the same surface area and deflection, a fowler would be my guess, though I'm treading upon unstable ground disagreeing with 411. With the rearward translation of the surface it seems that would give your surface more arm, thus a greater net change in center of pressure. Apples to oranges of course, but I found the pitch change with flap extension to be more objectionable in Cessna singles (fowler) than Cessna twins (split).
Standing by to be corrected.
