All things considered, it's pretty much wash when you compare the best loads in each calibre. The 9x19 is a little easier to shoot well (quickly) and offers greater capacity. Training/practice ammo is less expensive for the 9x19. The .40 S&W makes a slightly bigger permanent cavity. Certain models of the .40 S&W (reworked 9x19 models converted to .40 S&W) have been plagued with kB! issues even with factory ammo (less a comment on the .40 S&W than certain weapons chambered for it).
