Return to Question

I am using a function to compare over 100 variables inside of classes to each other an am curious if one method of comparing multiple condition statements is more efficient than another. I am currently considering one of these methods. I think the 'single If using And/Or' looks the cleanest but performance is more important. (my code is VB.Net)

Multiple ElseIf

If Not ClassA.num = ClassB.num Then
    Return False
ElseIf Not ClassA.str = ClassB.str Then
    Return False
Else : Return True
End If

Single If using And/Or

If Not ClassA.num = ClassB.num Or
   Not ClassA.str = ClassB.str Then
       Return False
Else : Return True
End If

Nested If

If Not ClassA.num = ClassB.num Then
    If Not ClassA.str = ClassB.str Then
        Return False
    End If
End If
Return True

Edit: Changed second code snippet from And to Or
