Who's your daddy?!?
In that case, I can tell you that I'm extremely happy with my two MP40W's. I have one at each end of my 125 (60") set for Reef Crest at maximum power and I love what they do to my tank. They have a very broad output so that I can put corals close to the pumps and they aren't getting blasted with a narrow stream. The also have a very wide intake suction. I can watch stuff drift along the bottom of the tank towards the pump when they spinning at high rpm. They're very simple to setup due to the wireless technology. You simply set one as master, any others as synchronous or asynchronous, and then program the master for the mode and settings that you want. That information is passed to the slaved pumps when you finish programming the master and you're in business. Want to add another pump, simply set it to slave and you're done. The only downside for my money is money (they are expensive) and noise. If you don't position them just right they will vibrate and create noise in the room. Good pumps but spendy.
