For authenticated file transfers, is there any reason to use ftp instead of the ssh file transfer protocol (sftp)?

Depends on how they're authenticated. If your customer has a shell account on your machine, you're right. But some ftp servers that authenticate against, say, ldap or a database. Keeps your customers out of /etc/passwd.

You could certainly do this for a few files with http. But when there are ~2000 files totaling ~100 GB, and the customer is of the old school who probably doesn't know (or care) what torrent is, ftp is the way to go.
