Are you having issues with Filezilla? I have been using that forever, and love it. Used CuteFTP way back in the day, and it was fine. Looks like it's a pay program now.
Agreed, I switched from FZ to winSCP and never looked back. The interface is better, but one of the main reasons was that FileZilla does not encrypt usernames and passwords whereas SCP does.I use winSCP. Earlier I was using fileZilla but winSCP is much more user friendly than fileZilla.
