Don't have either but have done some research:
Power Poles: Con works off of hydraulic pump and there have seen some issues with pump problems. The whole unit goes down when deployed a little more co-angler friendly than the talon.
Talon: works off of boat battery with very little power draw, can be easily removed, but could get in the way of a co-angler because when the spike is deployed the top stays the same height.
The talon is lighter in weight than the Power pole with the pump.
When I get ready to buy it may be a hard decision, time will tell about the talon since it is new on the market.
Just my 2 cents!!!!!!!!!!!!!!!!!
