Diablo – What’s the benefits of doing Adventure Mode/Bounties compared to Rifts

diablo-3

I am new to the end-game and I am trying to understand the pros and cons of doing adventures + bounties vs rifts.

According to this post: What is the point of Nephalem Rifts?

Rifts seems far superior than doing adventures + bounties, so my question is:

What's the benefits of doing Adventure Mode/Bounties compared to Rifts in Diablo 3?

Best Answer

One of the main reasons people do bounties (besides getting keys to enter rifts) is certain legendaries can only be acquired from Horadric Caches, which you receive upon completing all 5 bounties in one act. Some of these legendaries are very important for end game. For example, Ring of Royal Grandeur is a must for most, if not all, end game builds.
T6 (Torment 6) Bounties now guarantee an act legendary (Thanks to @Frank for this info).
