I wonder which FTP client do you guys use? I'm using Filezilla and am fine with it. Before I used SmartFTP, but it is no longer free, so I went with Filezilla.
Filezilla is the best and its free. However you need to be careful because I faced malware problems on my site and I suspect that my passwords and other info stored on Filezilla was compromised. So now I've stopped using it and I just go online to the cpanel of my webhost and use their file transfer system.
I'm using FileZilla for the last 3 years. Before that I was using Total Commander, but I hated it for the ugly interface.
I used to use FlashFXP, but now I've started using CuteFTP. I don't think it really matters what FTP client you use to be honest, it's all personal preference.
I use Filezilla as my dedicated FTP client, but the majority of the time I just use the ftp/sftp module in Notepad++
