I don't think there is a difference of opinion here at all. The fact is the more you can afford the better skimmer you are gonna get.
I have a 75, and i use the AquaC Remora Pro with a souped up (mag 7) pump driving it. I've also moved it to the sump and converted it to work like an urchin. Of course, if I had 2 gees lying around, I'd get the deltec that has the automatically cleaning brushes for the collection tube. Would it make a huge difference? Maybe not, but there is no question that the skimmer is all important, and price does matter.
