Based on questions and comments in various forums, 12v Pertronix units are quite reliable and seem to work well with very few complaints. I believe you could attribute that to the fact that since the solid state logic used in the module needs a very stable voltage supply, when 12v is dropped down to the required level there is a lot of forgiveness for underlying voltage issues because you are starting with a much higher voltage supply than needed.

6v units are hit or miss. It seems that if the overall car is maintained and reported to run well and is quick to start then logically it must be that the car and particularly the 6v electrical system is kept in good condition. There is probably very little voltage drop to contend with and complaints on those Pertronix conversions seem to be few. If that is the case, it would also stand to reason that cars with varied reports of starting, running or driving issues might also have less well maintained electrical systems. When a Pertronix is put on those cars in trying to solve other issues they seem to have a fair number of complaint and failures to the point many of them are soon reverted back to points. Suspect voltage drop thru poor connections is a big part of those issues when you do not have much extra to start with.
