I've got several distributors, with slightly different curves. Two have points and one is Pertronix. I have the Pertronix in the car with the new engine, because it was the latest and was curved for the new engine. After 2,000 miles, I can say that is no better or worse than the points. But all of mine are rebuilt, so I have an advantage of working with all new parts.
I do keep a complete plate, with re-gapped points and condenser mounted to it, ready to be replaced by removing the two screws and dropping it into place, should the Pertronix ever fail. Jeff made that up for me when he converted the last distributor over to Pertronix, just in case.
