Yea, stream is what's generally preferred for personal use, as it has the lowest chance of getting back onto the user. It what you'll usually see on an officer's duty belt.

For riot control a fogger is preferred for the opposite reason....it gets everywhere, so you can spray a lot of people in one instance. The downside though, is that it will get the user too. With a fogger it's best to have some sort of protection (either a full face shield or, better yet, a gas mask)
