A system with one pump per bag will definitely be the fastest, regardless of the type of whether or not the pump is a flexible vane impeller like the Jabsco or Johnson or an aerator like the Attwood.

From a plumbing and installation standpoint flexible vane impeller pumps are the easiest, but an aerator based system can be just as fast and functional if installed correctly.

We've been VERY impressed with the Johnson pumps so far, they're significantly faster than the Jabsco, and if you already have a switch, the cost savings is considerable (even if you need switches, they're still cheaper than the Jabscos).

Either one is a great pump, it's just nice to have a choice now.
