I can't speak for your specific year and model, but I will say that I bought a 123Ignition distributor a long time ago for my 1972 1800ES and I have been nothing but happy with it. I compared the 123Ignition and the Pertronix, and it was clear to me that the 123 was right for me. If you have worn blocks that trigger your points, the pertronix will fix your issue. If you have wobble in your distributor shaft, the pertronix will still allow that wobble to vary the pulses to your coil. I bought the 123Ignition and got a BRAND new distributor that had zero play. I noticed a nice difference and found that when I'd poke along at idle in first gear (typically in parking lots with a manual trans), the car wouldn't lurch when I rode the brake.
One time when I took my car to work, I pressure washed the car from underneath. Well, wouldn't you know that I hit the distributor just right and shot water between the cap and body enough to just about fill the distributor. I blew it out with shop air and the car still wouldn't start. I swapped in the original distributor and brought it back home. The next week when I called up the place I bought it from to order a new module, the guy suggested I give it another try now that it had a day or two to dry out. I put it back in and it has been working flawlessly ever since. It really is a very nicely made unit.
I know that the price of admission was high, but for me, it was worth every penny.
*EDIT*: Please realize that my 1972 1800ES still has D-Jet. So, it has a second set of EFI trigger points in the bottom of the distributor. I spent just a few dollars more for that version of the 123Ignition distributor. But, again, I had piece of mind that I wouldn't really ever need to worry about either set of points again.
BTW: My unit is old enough to have the 16 position switch on the bottom to choose one of the 16 different timing maps. I've seen later units that had USB plugs, but again that was probably over 7 years ago. I don't know what they are using now.
