Cons of a P-P-Pump...

1. No plug N' Play ability. All tuning must be done by hand. So ease of adjustment is difficult. VP44 enhance I just push a button and never get dirty...
2. Timing is fixed. VP44 has dynamic timing that varies to suit the load of the vehicle. Better for MPG numbers. So it requires special tools to reset the timing a P-Pump. Where with a VP44 you can boost timing with enhancements...

Pros of a P-Pump...

1. Yes a P-Pump will out last a VP44 pump...
2. There are cheaper to build power with...
3. Are fairly easy to work on...
4. Engine oil lubricated... Compared to fuel lubricated on the VP44...
