When each is wrong
Stream in a hallway you must then walk through; foam in wind at range; fog anywhere you cannot leave. Most people carry a stream and keep foam at home.
Defensive sprays are restricted by canister size or formula in some states and cities and are not permitted in airline carry-on bags. This page is not legal advice; check your local rules before ordering.
