I run an electronic ignition in my 4cyl porsche. It is programable with a laptop, so I can change the curve very easily. You can do things like 0 deg advance below 500 rpm for easy starting, then have advance say 10 deg from 500 rpm and ramping *down* to the normal idle and then above idle your normal advance curve. This trick of increasing advance when you go below target idle speed helps stabilize a low or cold idle. This helps the porsche since it has no choke.
What else? Rev limiter if needed, not much use in a packard though. The better electronic ignitions control coil charging by time and not just angle. This allows you to run a hotter lower resistance coil.
In some cases, electronic distributors may be cheaper than good oem parts (porsche world this is a problem)
Some electronic ignition systems also incorporate data acquisition if you are tuning or doing dyno runs.
That being said, points and condensers do work pretty well.
