Another reason to use zetcd over Zookeeper is security. I don't believe it is possible yet to use TLS for Zookeeper-to-Zookeeper communication (clients can connnect to Zookeeper using TLS). The Jira covering this feature [0]. This will increasingly be a problem for those running Zookeeper for Mesos, Kafka etc. from a security and risk point of view.
