Pretty sure it would have a different crankshaft, cam for points, vs key for notched timer rotor. But I haven’t actually looked it up.
OK, Motorola Amplifier (breaker points) vs Prestolite (breakerless) Pulse Pack. They are pretty similar in the way they work, except for the triggering method. Both systems use that POS distributor cap. The Prestolite had a nasty habit of suddenly stopping dead in the middle of nowhere and working just fine by the time you got it towed in. I found it hard to like for that reason. On the other hand the Motorola system had the points. I don’t see that as a big problem because the distributor required maintenance service anyway. The points themselves never burn and pit their contacts like “regular” breaker points. But with many hours running they wear mechanically just from opening and closing a few million times.
So it is mostly a matter of choice and opinion. My personal choice would be the Motorola. Matter of fact I had a new one on my own boat back in “The Day”, and it never gave a bit of trouble.
