Wim, 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. When I have asked why various manufacturers changed to the butterfly, this is the response I have been given. "Everyone" uses butterfly now (Yamaha, Kawai, Beckstein, etc), and presumably there is a reason beyond just copying Steinway. In raising the question, I was hoping to get a little more objective discourse going on the subject.
