Which configuration is "better" really depends on your use-case. Failback is a nice feature when you have, for example, invested more money into the hardware of your primary broker since failback ensures the primary will take over as soon as it comes back online.
Keep in mind that running a single pair of brokers with replication is not recommended due to the risk of split brain. The recommended approach to mitigate split brain is by using ZooKeeper. See the "zookeeper-single-pair-failback" example for more details on that.
