Bob, yours is a wide open question to which there are as many "opinions" as posters lol mine certainly included. Kind of like Fox News "We report you decide" I will lay some basic engineereing info on you and then YOU DECIDE.
1) Many who convert to elec ignition report improved starting and idling, which although antecdotal, is based in sound engineering. So long as the elec ignition is working properly???????????????? it provides fast positive coil current switching as opposed to the bouncing and ringing of mechanical and ever burning carboning and pitting contact points.
Sure points are fine and have worked and will continue to do so fine and economical for years and YES an elec ignition is expensive and can FAIL. Im ONLY saying "as long as an elec switch is working" it pretty well stays the same and provides fast positive efficient coil current switching versus points which continually burn and carbon up and pit AND BECOME LESS EFFICIENT AS TIME GOES BY. BUT elec ignitions fail grrrrrrrrrr and are more expensive !!!!!!!!
2) Will it gain HP ??? Probably not much if any at all versus a good set of clean properly adjusted mechanical points.
3) ONE BIG PROBLEM with an elec ignition is if it stops youre dead in the field while if points go bad you can clean n file them n get back to the shed.
4) ELEC IGNITION IS NOTTTTTTT ANY MAGIC CURE ALL ELIXIR to fix other problems. If the engine has other problems the installation of elec ignition alone DOES NOT FIX IT.
5) In modern autos their high energy elec ignition systems can last for years n years n miles n miles trouble free but the tractor change over systems just dont seem that reliable.
NOW HERES THER DEAL: To get the most bang for the buck and utilize all the advantages an elec switch has to offer I SUGGEST YOU COUPLE IT WITH A HIGH ENERGY COIL (i.e. not just the old stock coil) . If that is done then you can indeed DISCHARGE MORE SPARK ENERGY ACROSS THE PLUG GAP then with the old stock coil and points n condensor. In higher compression and pulling tractors that becomes more advantageous then in our putt around and parade tractors.
Soooooo they cost more and if they fail youre dead (versus points you can file n get home) but improved starting and idling can take place SO LONG AS THEY WORK and if coupled with a high energy coil you can indeed discharge mnore spark gap energy. A good set of points is fine and can start a tractor even at extreme cold temps just fine IF ALL ELSE IS OKAY and are cheap and worked for years. You likely will NOT observe any noticeaBLE HP gain.
