Your point about coils being better arises once you introduce electronics into the equation.
In the old days a coil would just be for example 10 turns primary, 10000 and your output HT voltage was a given for each coil.
When you introduce electronics, each component has a tolerance and it can lead to those cumulative tolerances working better with one engine than another, perhaps due to the timing pickup being slightly more advanced or retarded than another on a particular engine.
Even some of the most simple engines now have CDI ignitions.
It is also likely that the manufacturer would improve the output voltage of a coil as a production update while attending to the original problem of why the coils were breaking down.
The improvment would be a negligible production cost to them.
