Many and none at the same time :)  A better question would be "What are
you looking for in a Virtual Environment".  I've been using both for
quite some time now, although I haven't used XenSource, the commercial
implementation of Xen.  It also really depends if you are using your
virtualization in a commercial environment or just as a "hobbyist".

At work we have the whole VMWare Infrastructure thing going on,
Fibre-Channel SAN and all.  For personal stuff I use Xen because I
prefer Open Source, like the performance of para-virtualization (VMWare
doesn't support that yet, but they are working on it with IBM, RedHat,
and XenSource -->
http://www.vmware.com/interfaces/paravirtualization.html ), and I don't
use Windows.

If you do a google search for "xen vs vmware", many good articles come
up.
