So why is an impact screwdriver great for screwing into oak,

I can't recall recommending an impact driver for such a task. I've used
one to get rusted in screws out of oak.

You're only trying to hold plywood to a metal frame WTF do you need an
impact driver for?

Are you sure you guys are talking about the same tool?

Yes i meant about using an impact screwdiver,
like the blue battery one in the picture,
it drives screws into oak.

But would it be suitable for driving self tapping screws into metal
framework?

They are often used for fixing drylining to metal studwork - usually
without pilot holes. I can't see any real difficulty unsing self tappers
into more substantial metalwork - just take care not to drive past "done"

Or is there a reason to use a electric drill on low torque setting?

If your cordless drill has a torque limiter and it can muster enough
torque to start the screw, then you can use that if you are worried
about over driving.
