In a fanfiction where the Sandaime survives the Chunin Exams, Konoha would be a very different place. His wisdom and experience are invaluable.

And the relationship between the different ninja clans might be more stable with his leadership still in place.
The story would take a different turn. Naruto would have more support. The Sandaime could help him train better and understand his powers more. Also, the threat from Orochimaru might be more easily managed, which would change the whole dynamic of the series.
