Comment(by ahocevar):

 @erilem: this surprises me: pagePosition should be more efficient in most
 cases, because it does not always have to bubble up the offsetParent
 hierachy. The only impact I could imagine would be the extra function call
 of getViewportElement in getMousePosition, but this should only be called
 once after scroll position or page size changes, and have no impact on
 drag performance. I'd be interested to hear where you experience extra
 overhead.
