What are the quests that provide the best lifetime benefits?

Question

I want to know which quests can provide the best lifetime benefits. For example

• The Inquisition Quest (provides the benefit of getting blessings faster)
• The Postman Quest (provides cheaper boats and access to more mailboxes)

P.D .: I edited the question following the comments. I hope it is more understandable now.

Comments

I believe the downvotes were caused by the fact the question was not clear, rather than just not knowing the answer. When they review the edited question they will have a chance to reconsider the vote.
