I use the locks my insurance company recommends. That's who it's there for anyways.

The other side is "career" thieves will know how to pop-can shim a lock but most of them are not going to use or break out a set of picks. One main reason it's an additional felony charge if you get caught using them. So a _slightly_ better lock is sometimes warranted for outdoor applications.

The final piece is they'll just steal a car and then drive that car through your shop front to get what they want. Up here in Northern California a gang pulled off the same heist as the movie "Casino." They drove a van up to a wall and then knocked out a small segment of the wall to gain entry.
