Qt based classes are wrapped using SIP.  SIP is used because it knows about 
Qt's metaobject system.
Bridge wrappings are created for all wrapped VTK based classes so they can be 
used in Qt based classes wrapped with SIP.

I would expect them to be better.  Swig doesn't have knowledge of Qt's 
metaobject system.
You can see VTK/GUISupport/Qt/Testing/Python/TestConnection.py for an example 
of using a python method (annotated as a Qt slot) as an event callback.

There are no known issues.  But I'm not sure how much its been used beyond the 
tests made for it.

Yes.
