Events Question

[Amremad]

What's is deferent between the next two code

    Private Shared WithEvents docEvents As DocumentCollection
    Private Shared Sub docEvents_DocumentDestroyed(sender As Object, e As DocumentDestroyedEventArgs) Handles docEvents.DocumentDestroyed
        MsgBox(e.FileName & " docEvents_DocumentDestroyed")
    End Sub

    <CommandMethod("StartEventHandling")> _
    Public Sub Asdkcmd()
        docEvents = Application.DocumentManager
    End Sub

 and

Private Shared docDestroyedEvent As DocumentDestroyedEventHandler
    Public Shared Sub OnDocumentDestroyed(ByVal sender As Object, ByVal e As DocumentDestroyedEventArgs)
        MsgBox(e.FileName & " OnDocumentDestroyed")
    End Sub

    <CommandMethod("StartEventHandling")> _
    Public Sub Asdkcmd()
        Dim docs As DocumentCollection = Application.DocumentManager
        If docDestroyedEvent Is Nothing Then
            docDestroyedEvent = New DocumentDestroyedEventHandler(AddressOf OnDocumentDestroyed)
            AddHandler docs.DocumentDestroyed, docDestroyedEvent
        End If
    End Sub

and what's the best for use
