in CCNA & CCENT
I realize I should probably know this from my CCENT studies, but I still a little confused about what the benefits of using one over other is:
ip default-network 10.0.0.0
vs.
ip route 0.0.0.0 0.0.0.0 10.0.0.0
ip default-network 10.0.0.0
vs.
ip route 0.0.0.0 0.0.0.0 10.0.0.0

So the big difference is that ip route 0.0.0.0 0.0.0.0 10.0.0.0 creates a static route only on the router it's created on, and the default-network command is carried by the routing protocol?

That's correct - I also took a snippet from on of Chris Bryant's articles about the topic
"When deciding whether to use a default static route or a default network, keep in mind that if you want the routing protocol to propagate the default route, the ip default-network command will do that for you. But if you want only the local router to have the default route, a static IP route is the way to go."

This is what I initially thought, but I wanted to be sure.
