No, they are not. On the FTPS server you can require TLS encryption of
everything, auth, data, control channel, nothing, or combinations of them.
In this case you would require auth+data which would mean that your
control channel is in the clear, but the username/password exchange and
the data would be protected. You could also use an SSL client certificate
as authentication and negate the need for the password to be sent
