The important difference, at least as far as a windlass gypsy is concerned, is the size of the link.

Chain has two critical dimensions, the diameter of the metal that makes the link, in this case 3/8" and more critical for fit in a gypsy, the length of the link. G4 links are longer than BBB links and will not fit in the same gypsy, at least for the same metal diameter.

I have a SL windlass and I can fit 3/8" BBB or 5/16" G4 which have almost identical link lengths. I cannot use 3/8" G4 in that gypsy.
