Among them, vsftpd is famous for its security and performance, and ProFTPD wins by many features, the performance and features of pure-ftpd are basically not updated. Generally, vsftpd is safe, stable, simple, and universal. If you have special requirements on features, you can select ProFTPd. Pure-ftpd is not applicable on some platforms.
