Just what it says on the tin, which one do you use? Why?

I don't do a lot of FTP, so I stick with Internet explorer.

I use Smart FTP and I really like it.

Smart FTP

I second SmartFTP if you're on Windows.

Thanks.

I'm a big fan of Fetch.

If you don't need SFTP then SmartFTP is a good choice, but if you do then FileZilla is okay. The interface is kind of clunky and it lacks a lot of the features of SmartFTP, but it has a one or two that (last I knew) SmartFTP doesn't (like sorting files on the remote host by type).
