MSD, can you tell the difference?

I have points, electronic, and MSD systems. They all run well, but hands down the MSD runs best, starts easiest, and makes the most power. Whether to use it or not is your won feelings. I know how to make them all work well. Some don't have that luxury. If a std ignition equipped engine is tuned properly it will be more than enough in most circumstances. However a properly tuned MSD will give side benefits like idle quality, economy, and better cold starts in the climates that need it. Is it aways needed, no. But it helps.
