Lets just say I am going to inject 3 externals subnets rather adding them to
an area via a network command. Is there any difference with creating a
summary versus a external LSA?

A lot depends on your topology, the size of your OSPF domain, the number
of exits to the Internet, and so on.
For example, suppose you had a small company network of less than 100
routers and a single egress point to the Internet. There would be no
point in injecting external LSAs into OSPF and filling up routing tables
with unnecessary routes. A single default route pointing to the ASBR
would suffice.
The answer is, it depends.
