If they are both in good shape and make sufficient voltage to fire the spark plugs there should be no difference. Of course, if the battery voltage sags under the starter motor load to where there is insufficient voltage for ignition, then you have an ignition failure. That's why I like mags, they just fire and don't care what the battery voltage is. The other advantage of a mag is hotter spark at very high speeds because the primary voltage they generate continues to climb as speed increases, while a battery ignition system is limited to the voltage produced by the battery and generator charging it. That's why mags are sometimes used in racing engines, but you're never going to approach those speeds on a tractor engine. Brian
