SmartFTP - for some mysterious reason never finishes a transfer but does it over and over again
CuteFTP Home - worked fine, except resuming didn't
CureFTP Pro - LIST command doeesn't work always, crashed frequently, takes up insane amount of system resources
CoreFTP - extremely low download speeds, but otherwise everything worked so there seems to be nothing wrong with the server itself
I really, really don't have time for this.
