I on the other hand have not used MarkLogic.

BaseX and eXist seem to be the most widely used. There is also Zorba, 
although I found it difficult to set up, and Sedna, which seems not to 
be actively maintained.

Usually I send people to BaseX in the first instance, as the easiest 
to get started (it's written in Java and has a GUI, and can be used 
also from PHP, Perl, etc.; most people I've spoken with seem to have 
their first query running within a few minutes of downloading the 
software).

For a mixed relation + XML model, Virtuoso supports XQuery, although I 
have not tried it.

What I believe is most important is to keep any software-specific 
extensions isolated from the main queries, so you can easily switch.

I should really update www.w3.org/XML/Query/ to reflect XQuery 3.0 
reality.
