The end result with both SSL replication flavors is the same.
Both encrypt the replication traffic between your directory servers.
The client cert method, when properly implemented, will make life more 
challenging for a prospective attacker who would like to impersonate 
your replication manager identity.  In that sense, it is more secure 
than simple auth with SSL.
