I also prefer magnetos. They are definitely a little more complicated than battery ignition. A magneto produces a hotter spark the faster you turn it. However, at the RPM's that these old girls turn, that is really not a factor.
However, their true value is that regardless of battery condition, even a dead battery, the tractor will start and run if the ignition system is a working order. A battery ignition spark will degrade with lower voltage from the battery. Also for cold starting, a magneto can't be beat. Understand that the coil is nothing but a "step up" component. the lower the input voltage, the lower the output voltage. When cold starting a battery ignition, the amp/voltage drop due to the starter drawing current, will cause the spark to be "colder" and weaker. A cold start is when you really need a hot, strong spark, and exactly the worst time since you have significantly reduced voltage due to the starter draw on the battery.
Once again, mags are more complicated and require more maint. They are not for everyone. I prefer them.

The whole experience can be marred if one moves too fast and makes too many assumptions that they can just use "as is" some parts they should be closely scrutinizing and possibly attended to.
