I mean, both of those get things right. XAML&#x2F;WPF tries to make the interface cleanly human editable in code, but is incredibly verbose, and the &quot;can be human editable&quot; constraint ends up being &quot;is only human editable&quot; pretty quickly. Interface Builder is a lot more intuitive and powerful, but it&#x27;s more of an all-or-nothing affair, in my opinion.<p>Beyond that, though, they have way more in common than they do different. I&#x27;m not sure it makes sense to talk of one of them as a better <i>model</i> than the other, versus maybe a better <i>implementation</i> of the same workflow.
