Planning to get truck coils, round or square? Iam planning to replace my current stock coils with a set of truck coils. However Iam kinda confused which of the two coil types (round or square) is supposed to give a stronger spark?

The best coils are Mitsubishi and they are GM part #12558693 and bracket #12569188. The wires are different and I dont have a part # but if its any help they have a bar code on them and its #208059 then you just need some msd truck wires. The mitsu coils are the better ones the delphi are not as good. Worm boy I think posted this a long time ago so I remembered it when one of my coils went bad and I by luck ran into some at the dyno on the same day just laying there on his bench. I searched it and sure enough it was the same ones and cheap so I did it.
