That's a lot of difference. Heavier bullet, travelling faster, costing significantly less and far easier to find, and feeding a myriad of platforms.
380acp is fine and it's got a purpose. There certainly are a number of very convenient carry guns that run on 380. But it's not a useful caliber for me, personally. Not that anyone needs to share my take.
