3.4.4 had a particularly unfortunate bug (ZOOKEEPER-1550). Users not running Oracle JDK (e.g. OpenJDK or IBM JDK or JDK 7) could easly fail to connect to a ZooKeeper instance NOT set up for SASL/secure communication. This is what 3.4.5 fixes, primarily. The version of ZK you use certainly matters, so far as HBase users should avoid 3.4.4.
