At the risk of being redundant, I'll say x3. And for the reasons most have said - it's not performance (per se) it's reliability and driveability. Mine had HEI from the previous owner but started after sitting for over six months, it idles smoothly and starts on the first crank every time. I had an older Porsche and when I switched to electronic ignition, it idled smoother and revved smoother. If you truly enjoy doing your own tune-ups, including setting point gaps and dwell, feel free to have fun. If you're looking for care-free driving, electronic is the way to go.
Don't get bashful on us, Hotrod. I've found your "opinions" to be both useful and highly and substantially factual.
