Generally the lower resistance will lead to a hotter spark if it is needed. But an ignition system only builds voltage to the point where it flashes over somewhere, we hope across the plug gap.

Aftermarket coils, many times, had a much lower resistance causing higher current flow through the switching transistor of OEM ignition systems, shortening their life. Certain coils could burn out a Mopar ignition box, for example.

Capacitive discharge is something else, though, and there appears to be a need to get the impedence right for them to work best.
Thus matching the coil to the box CAN BE helpful.
