Any Coil that performs dramatically better?

theory says that you only need enough spark to overcome the potential and the conditions that exist i.e cylinder pressure, mixture etc. the dyno proves this is true. arc welder coils are, like so much of this other stuff just voodoo and shiny beads and trinkets. if your motor is conventional... i.e normally aspirated, less than 13 to one CR, and running on pump gas of some sort then the coil you buy at napa for 16 bucks is every bit as good as the best piece of garbage that MSD makes from an electrical standpoint of running your motor.
structurally is a different deal. if you have a harmonic issue such that you are vibrating the insides to bits somehow, then a solid potted transformer type will be a better solution.

I had my MSD box rebuilt and the guy that did it suggested a coil from Auto Zone. I am running that coil and did not see any problems with it on the dyno..

each ignition type and each transistor ignition will have its own requirement for coil internal resistance which is on the sheet of paper that was in the box when you bought it and you threw away without reading it.

I've used several different brands of ignition box with the matched recommended coil, never had a problem, never noticed a difference between them. For me, it didn't make much sense to run a cheap coil with a high dollar box and expect it to work right.
