Right, rsync is unidirectional.  I use it with various flags for just
that purpose.  Some helpful flags are --recursive and --update (see
man page).  --archive is a good one too.

For directories that I need bidirectional synchronization, I use
unison.  It puts both host destinations in the same state moving the
newest files from one to the other.

By the way, both can run over ssh.
