If by 4BSD networking you mean Ethernet, "cluster hardware" or CI, is
much faster.  Also, it lets you hook up to DEC's HSC70 (or the slower
HSC50) mass storage controller.  I don't know if this will apply to
Ultrix users, though, since the HSC70 somehow provides support for the
VMS (Files-11) file system (or does/will Ultrix support mounting a F11
disk?).
