I don't have either one, but I do know when I was considering them for a bass boat I was more in favor of the Talon due to simplicity and not having to figure out how to put the hydraulic pumps inside the bilge area. The Talon is a self-contained unit that you can take on and off much easier than the Power-Pole.
Power-Pole hit the market fist, then Minn Kota refined the idea.
