I have two VBox VM's 1) is my Drupal development, 2) is my Drupal production.

I would what is a good or best single FTP or combination to use. I want to publish from the dev to the pro VM:

1) filezilla - GUI FTP and SFTP Client,

or

2) yast2-ftp-server - using pure-ftpd or vsftpd with gftp - Multithreaded FTP Client for X11

or any other recommendation?
