I am a huge fan of WS_FTP, but there is no Mac version. On their site (and a bunch of others) were a bunch of recommendations for Cyberduck, so I tried that. And I think it sucks. :\
Anything else out there that's better? I'm looking for something that does left-right windows (left -> local, right -> remote) and ideally has integration so that I can click a file and upload it directly from Finder, ala WS_FTP's browser integration in windows.
Edit: Though I think I can map an FTP folder in Samba and just mount it as a share, eh?
