For years, FTP (File Transfer Protocol) for basic file transfer has been a standard and still exist till today for the most use. But there is a problem, FTP servers have no security when connecting to, or files are encrypted or authentication, so we could jeopardize our privacy but we are connected through a VPN.
To solve this security problem in environments that require it, we can use servers SFTP (Secure File Transfer Protocol).
SFTP is a file transfer protocol that uses SSH (Secure Shell) to secure the commands and data transferred between the client and the server, so they are no longer vulnerable to eavesdropping, tampering or counterfeiting.
With SFTP, the data transferred between the client and the server are encrypted, preventing unauthorized users from accessing them. SFTP should be used when you need to transfer sensitive or critical nature between a client and a server configured to use SSH server for secure data transfers.
SSH File Transfer Protocol, is completely different from FTP (File Transfer Protocol). SFTP was built from scratch and add the feature to SSH FTP. Just use a communication channel, send and receive messages in binary (and not text format as does FTP).

What do you think about differences between FTP and SFTP? Which one do you use most?

FTP protocol should not be used anymore to transfer files, or only with SSL/TLS encryption using FTPS.
But SFTP is faster to transfer files, and support ssh-key authentification instead of basic passwords, which make bruteforce not possible.

FTP and SFTP are 2 totally different file transfer protocols and also the major distinction between the 2 is that the security related to the file transfer. FTP was the primary file protocol and is a smaller amount secure, whereas SFTP stands for secure file transfer protocol, and because the name suggests is safer than FTP.
