When I'm working on Windows, SmartFTP is my favorite FTP client. Along with UltraEdit, it's one of the few commercial utilities that were worth paying for. You'd think that the free FTP utilities would be good enough, but SmartFTP has so much polish and so many small enhancements (especially when it comes to handling multiple connections, auto-resume, remote file editing, transfer queuing) that it blows everything else away. That being said, I'm still on version 2.0, while the current release is 4.0. I can't comment on how much better or worse it's gotten.
