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 

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.
