My last investigation into costs, the MSDs were more expensive than the OEM (other than the dealer) coils.
With stock or lightly modded cars, the higher potential of the MSD coils wouldn't make much difference. It'* the other end of the spark plug debate. As long as there is enough spark to jump the gap, that'* what is needed.
Resistance ratio, and turns ratio are not necessarily equal, unless we know whether or not the same gauge wire is used for the primary and the secondary.
I agree that by all indications the MSDs specs indicate more potential. Whether it is noticeable in stock/lightly modded cars in everyday driving is up for debate.
