What you're talking about is a major difference with transistorized ignition. Stock ignition makes a lot of amperage - which causes burnt electrodes and points - transistorized ignition makes higher voltage - lower amperage spark. And thus less wear.
But the best part of trans/ignition is that it burns through carbon deposits and actually cleans them away. That's why trans systems start easier and are less prone to missing.
I have an old heath kit ignition system. It has a switch to allow CDI or normal ignition. When I first turn it to CDI it misses a while until it cleans the plugs of carbon and then runs great.
CDI and Transistor systems are not the same however. CDI is actually much too strong - it's high voltage and high amperage. It will burn wires out, cap and rotor electrodes, and increase plug gap quickley. I've experienced early CDI systems that wires only lasted 6 weeks on.
All modern ignition systems are transistor systems - they're pretty easy to build using a heat sink, large transistor, 1 diode, and a 40 ohm resistor. and the best part is you can use your existing points system - they'll never burn again with that 40 ohm resistor restricting current through them. But, as much as I like building these things - an 80's style ignition system is cheaper and can also be used with points.
