Comparing metric of two different protocols would be like comparing apples
and oranges.

I believe, the protocol that owns the native administrative distance wins.
Let's say, a router learns NET X via RIP & OSPF and you lower the distance
to 110 for the RIP route, router will install the OSPF route in the routing
table and not the RIP route.

I don't have any documented explanation for the behavior. But, it makes
sense the IOS prefers the native admin distance over the modified one when
both are same.

OK, rip had a hop count to 3 and ospf has a cost of 10.
Now who wins
