Choosing the right FTP client

I have used few FTP clients (since 1989 onwards) like WS FTP, SFTP, Cute FTP, etc.
Recently I have started using FileZilla.

FileZilla is a fast and reliable FTP client and server with lots of useful features and an intuitive interface - http://filezilla.sourceforge.net/. and its Freeware.

I like one particular feature of FileZilla: Use multiple connections to transfer files, (Edit > Settings > File Transfer Settings) when enabled, it can transfer multiple files at once. This feature can save lots of time (on a broadband connection) transfering files to a web server.

Though I still like to use the basic FTP client :-)
