Multibus probably has more "professional" quality hardware
manufactured for it.  Things like hard disk controllers,
ethrnet interfaces, .5 inch tape controllers, etc.  The
S100 bus has more "hobbiest" type interfaces: voice, low res
graphics, etc.  Multibus tends to be significaantly more
expensive than s100 for equivilent functionality.  In fact,
a bare WW board is about twice as much for multibus as for
S100.  Multibus has its own regulated power supply, which
moves regulation off the individual boards.  This may help
prevent heath problems on the boards, but it makes for a
much more expensive main power supply.  The definitions
that expand multibus to 16 data bits and 24 address lines
are justas ad hoc as the expansion of the S100 bus.
