Best FTP Software

I use FileZilla and WinSCP. I guess it really depends on what I feel like opening up. My IDE handles FTP connections to transfer project files back and forth, so only reason I ever use WinSCP is for transferring files direct to server for like backups and whatever else. As I post this, I realize, I haven't used Filezilla in months, and will probably end up uninstalling it. Huh, funny that.
