IMO there are a couple of reasons we developed and use s many drones, even before they carried weapons. One is that are very maneuverable. The other is that they have a great deal more resolution and provide more details that a satellite would.
Plus seeing from the side gives a better view than from straight down.

I don't believe the stuff about being able to count the dimples on a golf ball from space is real.
