Authenticity and the 'Definitive'

After listening to either the posted versions of 'All Along the Watchtower' or 'Try a Little Tenderness', post your opinion of which one can be considered the 'definitive' version upon which all others are compared. This is not necessarily a value judgement, but rather thinking about which is more likely to (or has already) become the standard.

More importantly, why do you think the way you do? What evidence in each version supports your opinion?
