Need to know the wattage/power consumption of the components you're comparing! Should be on the data plate(s) or in the literature. Once you have that, you don't need an electricity guru, you just need to do the math. Other than that, the thing that comes to mind is that propeller pumps like Koralias & WP40s generally produce a broader flow pattern than a bunch of narrow closed loop openings. So depends on what you're looking for in that regard too.
