There is little to no peak power to be gained between properly functioning ignition systems. Variation is usually within the accuracy limits of the dyno. Features and reliability are the main differentiators

How much spark crammed down a combustion chamber does it take until there's not any noticable difference?
You can spray it like an MSD, you can increase it, like a high voltage coil, and you can even multiple spray.
Yet in the end, it only takes one match to light a room full of gas fumes for it to explode.
That explosion travels at faster than the speed of sound.
The combustion pressure inside reduces voltage potential dramatically.
Keep in mind that even if you have a 60K volt coil; the combustion temp and compression dictate the
resistance the actual voltage will actually be.
The point here is that if you really have alot of cylinder pressure (compression) being created, you investigate into higher ignition systems.
On the other hand, if you're running less than 10:5 to 1 compression; why do all this ignition upgrades?
That is my question!
