The man said he wanted to carry freight and pax. The Chieftain will carry more, and the longer tail moment is nicer to fly.

Agree with you re the need for the Chief, but providing the cg is kept well forward, the Navajo is the nicer aircraft to fly (IMO).
Also quieter with the props further forward than with the Chief's props right next to the cabin
