The ip default-gateway command differs from the other two commands. It should only be used when ip routing is disabled on the Cisco router.
Unlike the ip default-gateway command, you can use ip default-network when ip routing is enabled on the Cisco router. When you configure ip default-network the router considers routes to that network for installation as the gateway of last resort on the router.
ip route 0.0.0.0 0.0.0.0
Creating a static route to network 0.0.0.0 0.0.0.0 is another way to set the gateway of last resort on a router. As with the ip default-network command, using the static route to 0.0.0.0 is not dependent on any routing protocols. However, ip routing must be enabled on the router.
Note: IGRP does not understand a route to 0.0.0.0. Therefore, it cannot propagate default routes created using the ip route 0.0.0.0 0.0.0.0 command. Use the ip default-network command to have IGRP propagate a default route.
ip default gateway is used on workstations within a given network so as to enable them route packets that are destined to address not within the same network.
While ip route is used to statically assign routes to other routers. Its usually used when one does not intend to use routing protocols especially for very small networks where an administrator can keep track of changing routes
