If you want a no nonsense ftp client the try Glub Tech Secure FTP. I find the UI (user interface) clean and simple to use. Yes there are many ftp clients to choose from but I like Glub Tech Secure FTP because is does what I need and it does it well, ftp. In my opinion this program doesn’t suffer from bloat. The noncommercial use *free* license is nice too.

My only (minor) issue I wish it had pop-up tips when mousing-over the icons. I was trying to use the ab icon as the CLI tool. I now realize ab icon is rename. A built-in text editor or program linking to an editor would be a nice touch for those quick edits.
