As far as High Volume and High Pressure oil pumps go, Mellings web sight stated that only more pressure could put more wear on a dist. gear and shaft. Both pumps have the same relief springs so the pressure is the same with either pump.
So with either pump wear should be the same if everything else is the same.
I like the pin style and have not any problems, I even shim my spring to a higher rate than stock to help the oil wedge in case of detonation.
