Can you explain in a simple way in which cases it is better to use app.fragment and in which support.v4.fragment?

The difference is that the version from android.app is tied to the version of the operating system and, depending on this version, may work differently. The version from support.v4 will always work the same regardless of OS version.
In all cases, you need to use the version from the support library. Also, android.app.Fragment is deprecated .
This does not only apply to fragments. Read about the support library in general.
