I am a big 9mm fan because it is small enough to fit in double stack mags without making the grip too big and it is still pretty powerful. It also cost much less than .40S&W so I can shoot a lot more of it.
If all ammo cost the same, whould it change what you shoot/own? I might buy a few .40s instead of all my 9mms but then again, I might not. The 9mm is a nice cartridge in its own right.
If you handload, all ammo sort of does cost the same. I reload for the revolver cals but 9mm isn't worth it because I can buy good ammo for LESS than I can make it.
