Anthony's input explains the advantage... if you use the BCC, then all
emails destined for the same domain can be grouped into one connection,
thusly reducing outbound mail traffic.  If the emails generally are bound to
different domains, then the difference could possibly be negligable in terms
of the actual transmittal.  Some mail servers may also be more optimized
when reading a single message out of the queue and then sending a single
email to 10000 people rather than reading 10000 email files out of the queue
and sending each one individually.  It's all a matter of where the overhead
is incurred by the mail server.
