I tend to like the ethos/logos/pathos model. Arguments from clever people can sound convincing because ethos gets mixed in. And anyone can temporarily confuse someone by using pathos. This is why it's better to have arguments externalized in a form that can be reviewed on their own, logos only. It's the only style that can stand on its own without that ephemeral effect (aside from facts changing), and it's also the only one that can be adopted and owned by any listener that reviews it and proves it true to themselves.
