Panic's "Transmit". Hands down. Only downside is that it sometimes truncates long filenames of downloaded files, but resuming is not broken, even if it does so. Second place goes to the CLI ftp client ncftp.
One more vote for Transmit! If there's any piece of software that embodies the philosophy behind Macintosh best, Transmit is it. No other FTP user interface comes even close to being so friendly.

For the real free FTP client I only can think of RBrowser
I use Fetch though
