I have one DA and two Ultegra dual pivots - I can't tell the difference between them. Had Campy Chorus w/Campy pads on one for a while worked fine. the Shimanos all have
Yokozuna pads on them and they are fine AFA I can tell and a really quality looking pad. I really don't use the brakes much, never have. I have wheels from the 80's on the Caylor thousands of miles on them that show no brake wear. OTOH I've bought bikes that had rims so brake worn that I'm surprised they didn't explode at pressure 
And the old Colnago has the original Campy brakes and pads and it seems to me to stop just fine so I'm guessing I'm not a good recommendation for advice
