Only issue which I had with the Pertronix was when my Chinese ignition switch left my ignition on all night (key was not in the truck). It fried the Pertronix module and melted the top (which is on the bottom) of the coil.
I changed back to points and noticed no loss in performance.
If Pertronix could address the key-left-on problem, I would consider trying it again, just to eliminate one more thing to maintain.
