40 ft. sailboat bilge setup

[DDabs]

My current bilge pump setup is:
-Jabsco 36960 bilge pump
-Rule superswitch

I am recently being let down by my Jabsco pump and rule superswitch. I am looking for an alternative. My bilge sump is fairly small, and I like the idea of having my external pump mounted high in the bilge. I have been looking a lot at the Whale Gulper and Gulper Grouper pumps, which seem like a more reliable, simple solution. Any input on these models? Both of my head shower drains go into the bilge and I like the idea of having a pump that is heavy duty and will not clog.

Also with the float switch, thoughts on a better solution to the rule flapper? Jabsco Air switch?

Thanks so much for any input.
