It's mostly a matter of what you're most comfortable with.

There were some problems with the interaction of Xen's network-bridge
script with various other components on RHEL (and I assume it also
happens on other distros), especially in complex setup (like vlan and
bonding). See 
https://bugzilla.redhat.com/buglist.cgi?quicksearch=xen+bridge+bond

While they'll be fixed (eventually), using default OS config files
instead of xen's network script results in working configuration. So I
simply stopped using xen's default network-bridge script for anything
but the simplest setup.
