What do you like best? Big bettas, big pectorals, . . . . breed what you like most.
If you want to breed female giants to regular sized males, you need to stunt giant's growth. Keep her in a smaller container and feed sparingly. While keeping the male in bigger tanks fed as much as they would eat. Hopefully by 5-6 months the regular males would be 4+ cm (body) and the females are no more than 5 cm (body).
