ip default-gateway works if ip routing is disabled and
the router is basically a host on the network like
your PCs, etc. You would turn IP routing off (no ip
routing) to bridge all traffic for example.
Using ip default-network would let you propagate a
route via IGRP/EIGRP or RIP to a neighbor router also
doing IGRP/EIGRP or RIP and all the rules were met
(IGRP/EIGRP especially - RIP just announces a 0.0.0.0
no matter what ip default-network is pointing to on
the router). ip default-network must use a classful
network address.
ip route 0.0.0.0/0 next-hop will forward traffic to
unknown networks. If you have 'no ip classless' and
your next-hop is a directly connected network the
0.0.0.0/0 route won't be used.
