I agree that the originals wore well after seating. It used to be well known among A owners. The quality of reproduction points began to deteriorate starting in the early 70's, as the larger American manufacturers stopped making points. Those poor repros that followed were made in Brazil and Argentina and were known for rapidly wearing blocks, hence the move to "modern" 1970's Ford points. Now, thanks to Model A vendors demanding quality parts, reproduction A points are very good, and the reproduction 1970's Ford points are inferior. So we have come full circle. At swap meets you can still occasionally find good after market original style points made in the fifties and sixties by the quality after market manufacturers. This link is to a page on Ford Garage that lists those points
