No, I do not have any examples; partly because I am speculating
instead of comparing implementations. However, an RTF can be
optimized for addition,  while a node-set must allow fast traversal
and direct (XPath-addressed) access. Many RTFs are not used 
as node-sets, thus this should make sense.

I know from experience that switching tree model in Saxon 6 changes
performance pattern. Instead of (or additionally to) having two
tree structures, it would make sense to use different tree structures
for node-sets and RTFs.
