Believe it or not, I AM open-minded. But . . since Pertronix gives very little hard data/specs - I don't have a lot to go on. I do know most if not all comes from China. They had a big recall lately due to a bunch of Chinese epoxy "Flamethrower" coils failing.
As I stated earlier - posts on these forums are just about always the same. Someone installed a Pertronix kit and tractor runs "better then new", or more "fuel efficient", etc. Also note that the specific version of the Pertronix is just about NEVER mentioned.
None of those claims make a lick of sense to me . . . so I have to "throw out the baby with the bathwater."
The gain in MPGs really mystifies me. I've had many old Chevys that I converted to HEI breakerless. I did it because it cost me nothing and saved me the bother of changing points.
My 1965 Bel Air with a 283 and Powerglide trans got 13 MPG with points and 13 MPG with HEI breakerless. NO difference and it ran exactly the same.
My 1970 Nova with a 307 and Powerglide trans got a whopping 14 MPG since the day it was new. Back in the 80s, I stuck in HEI breakerless in that too. Guess what? It started and drove exactly the same and still got 14 MPG.
Going backwards here - my 1972 MGB had a breakerless kit in it when I got it. It failed and I had to convert back to points. NO difference in the way it ran or with fuel mileage.
I suppose with breakerless-high-energy . . . if ever flooded the engine and fouled the plugs - the HEI would give me more spark potential and a better chance of starting. Never needed to find out though.
The standard "first-version" Pertonix Ignitor, if anything, appears to offer less energy then a standard 12 volt system with a resistor and 1.5 ohm coil. Pertonix tech department told me it MUST be used with a 3 ohm coil or it will burn out. They also told me that just recently they started offering a 2.8 ohm coil that gives better voltage. So it seems they also feel a lower ohm coil can provide more potential spark energy.
Oh well, maybe I'm beating a dead horse here. If someone believes their tractor is "better then new" once the Pertronix kit is installed - fine. I refuse to believe it - but also won't argue the point.

Today's Featured Article - Restoration Story: Fordson Major - by Anthony West. George bought his Fordson Major from a an implement sale about 18 years ago for £200.00 (UK).
