Which would you pick for an all-around weapon, both for carry, home, and range use?
Recoil mostly. They stated that a .40 is "snappier" even than a .45, which makes some sense to me being that it is a higher pressure round. But like i said i have slim to none experience shooting a .40. This info was coming from sources that shoot several thousand rounds a year and MANY people on this site would trust very well.
