I run two switches and pumps. Not sure where the info on Rule is coming (I think they moved to Mexico) but from what I have seen, it doesn't matter what pump you put in, they all go bad at some point and Rule seems to hang in there with the rest, most of the time, space dictates what goes in.
What I do care about is the switches, I use Ultra Safety System switches, they come in 3 different configs, one config has a built in high water alarm, the swicthes are expensive, but they last, and the last thing I want to do is root around some bilge every year.
I also run two different size pumps, mount same height, the smaller one handles the everyday load, then the bigger one kicks in if need be, you replace the smaller one more often and is cheaper. Just make sure the smaller pump is 1100gph and has an 1 1/8 discharge. Besides, if all goes to hell in a hand basket, there is not much difference between 3000 gph or 4000. You take on that much water, you're going down anyway.
Wire each pump (seperatly) on the auto side directly to each battery on the switch (with a fuse), and the maunal side to switches on the dash.
I am not fond of anything automotive on boats, and auto reset relays or push breakers are worse, there is no way of shutting things down if they short circuit other than disconnecting them.
