Messenger can allow for some losses in degenerate infra cases, given a given infra footprint. Also some ability to handle scale up faster as demand increases, peak loads, etc. It therefore becomes a use case specific optimization. Also hBase can run in Hadoop more easily, leveraging blobs (HDFS), etc. So, depends on your use case.
