Which FTP you would prefer and why?

my suggestion is file zilla. it is user friendly anyone can access easily. There is no complicated things in that.

Contrary to other opinions I'm not happy with Filezilla.

I prefer WinSCP on Windows (not pretty but full-featured) and Cyberduck on OS X.

WinSCP is nice because of it's decent SFTP and SCP integration, and synchronised browsing. Also, it integrates with Pageant so I can login to all my server via my ssh keys.

Cyberduck is also full featured, but with quite an OS X interface. Nice is the support for Amazon S3 and CloudFiles cloudstorage services.

The best FTP clients must offer an unparalleled level of control over not only the upload and download of files, but also the access permissions for files and folders.

Below two are my picks and my personal favorite is  FileZilla

1. FileZillaFast, secure and highly customizable, FileZilla is the best free FTP client you can download
2. Core FTP LEVery easy to use, with advanced features wrapped in a no-frills interface

VSFTP if want secure user SFTP for Linux and use also in windows by WinSCP.

I prefer FileZilla FTP because it is user-friendly.
