Ok, so is there any benefits to spending much more on the Lumenition?! Electric ignition is electric ignition, surely?!
Electronic systems do not like getting hot. Heat degrades their reliability, especially repeated heating / cooling cycles.
The Optronic system has the electronics all potted inside a nice finned aluminium heatsink which can be remote mounted from the engine, say on a ( relatively ) cool bulkhead
Any system mounted inside the distributor will be cycled from cold up to about 80 deg C as it is in thermal contact with the engine block only cooled by the coolant. Plus the extra heat generated by the switching electronics which will be on top of this 80 deg C.

And then there is the vibration problem inside the distributor all mounted on the cylinder block which also decreases reliability.
Are you going to notice this on a daily driver doing 15,000 miles a year ?
Well, at 40 mph average speed that equates to about 375 hours use per year. About 1 hour per day.
It only has to fail once.
