When to use master-master replication VS master-slave replication

I am using CouchDB as the noSQL database for the CRM solution. CouchDB uses master-master replication. Compared to this, mongodb uses master-slave replication.

As a little newbie to NoSQL,

I would like to clearly understand what are the benefits of master-master replication over master-slave replication.
