I use PPS-Pro on big tanks but pfertz/Excel on smaller tanks just to save the money as I wouldn't want to buy anything for a 100+ gallon tank that comes pre-mixed (I do use pfertz bottles for my pps mix cuz I'm lazy).
It's just what system you like the most as Tom Barr has pretty much proven that any of the major systems can produce good plant growth if done correctly.
