Personal experience: Slight edge in performance to the .380. But .380 has more recoil (especially in today's super light pocket guns) and all things being equal, the .32 guns seems to have an edge in reliability of feeding. With the ".45 is the best" culture, the bigger .380 is usally preferred since it is "bigger".
