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
