If you want to know how much output is impacted, then put your car on a dyno, set a baseline, then change the plug wires and do a second set of pulls.
That info would address this topic quite nicely.
As for: “How is the engine more efficient?”
It has a greater / larger / fatter spark to better (i.e. - more efficiently) burn the fuel & air mixture in the cylinders.

Yeah. How much better could they possibly be?
Its like putting an 80mm tb on a 78mm intake. It will only flow as much as the opening on the intake right? So how much spark is enough and how much is more then enough and isn't used?
What about the coil packs themselves? They will only produce so much spark anyway.
I have seen though that the MSD coil packs and wires are good for around 5-10hp/tq though.
