Walbro advertises their pump to draw ~7-9 amps for what our operating range would be (each). That would be less than having the lights on, even less than some aftermarket radios. I would imagine the parasitic loss (through the additional work in the alternator) is extremely minimal, and both setups would behave near identical from a performance standpoint.
