Does a “ hotter” spark coil even matter on stock distributor systems or is just a bunch of hype/marketing ?

A coil will only give enough volts to jump the plug gap. Its a law of physics.
Some engines, boost, high CR require more voltage to jump the gap so the coil will put it out to do the job.
But a stock engine is never going to see the full 40,000 volts of a 40,000 volt coil.
