Best view in a viewer is significant in the following cases:

• If the value being viewed is an object reference, the actual object’s elements and properties are shown, in real time, as an explorer view.

• If the value is a collection (a list or a record), the items of the collection are displayed in an explorer.

• If the value is a valid alias or a file object reference, it is shown as a pathname that can be displayed in different styles (HFS or colon-delimited, POSIX or slash-delimited, and as the Finder would refer to it), as shown in the illustration below.

• If the value is image data, it is shown as an image.

Otherwise, you won’t see much difference from source view.
