I can't really say from my own knowledge and experience that the butterfly 
performs better than the Schwander or other designs (the Baldwin, the 
Pratt-Read, etc). But I have heard it stated that the regulation of the 
butterfly (when it is regulated properly) is more stable over time, and 
that it produces quicker and more reliable repetition. We're talking 
highest level performance here - concert stage virtuoso stuff, really 
splitting hairs.
I can understand that it might be more stable, but, as you said, only when it 
is regulated properly. But because it is so difficult to get a precise 
regulation on a butterfly, as opposed to the screw adjusted reps, it would seem to 
me that having a rep that can be adjusted much closer, and easier, would be 
preferred. But maybe only by technicians, and not pianists.
