This isn't a fair comparison.

How about this: It would seem like there are people (standard XQuery  
instructions) driving multiple trucks (processors) built to the same  
standard. When you hook it up to the same trailer (a hierarchical set  
of collections/folders that contain documents), the thing you are  
pulling turns out to be different.

At this point I am not even talking about extension functions that  
basically do the same thing in each processor, but live in different  
namespaces. (And really, how many people in the real world write only  
standards based XQuery?)
