ftp would probably be faster as scp has to encrypt files first...but here is the advantage. encryption.

the syntax is pretty simple.

from localhost to remote server

Code:
scp filename  user@remoteserver:/path/to/remotedestination
and

Code:
scp filename  user@remotehost:/directory/
There are also a few fancy flags you can add.

see man scp

Code:
scp filename1 name@website:filename2
filename2 means that filename1 will be loaded onto the server and renamed as filename2 at the same time. Basically the syntax of a scp command is similar to that of cp. You have just to take in mind that to specify a remote path the syntax is
Code:
user@host:/path/to/remote/file
where the hostname (or IP address) and the colon are mandatory. If you omit the username, scp will try to connect using the same username as in your local machine. From what stated above, you can copy to a spcecific loaction on the remote server, by typing the path immediately after the colon:
Code:
scp filename1 user@host:/home/user/my_files/
this will copy your local file to the directory /home/user/my_files/ on the remote host. You can also use relative path, taking in mind they refer to your home directory on the remote server. If your home was /home/user in the example above, you could also do simply:
Code:
scp filename1 user@host:my_files/
Some useful options of scp are -p to preserve the timestamp of the original file and -r to recursively copy a directory or an entire directory tree. For example:
Code:
scp -pr /path/to/your/local/dir user@host:
Since I did not specify any path on the remote server (but not the mandatory ":" at the end) this will copy the local directory to your home dir on the remote host.

Finally, you may have some problem to specify file names on the remote server if they contain blank spaces. The correct way to do that is to double escape them so that a single escape character is passed intact to the remote server:
Code:
scp -pr user@host:"/path/to/dir\\ with\\ spaces/" .
moreover, this show you how to retrieve a directory (or a file) in the opposite way: FROM the remote server to the LOCAL machine (in this specific example to the current directory "."). Hope this helps.

They are two completely different things and they cannot be compared in term of speed. Theoretically ftp is faster, since it does not use encryption, but I think that the speed of the transfer is mainly due to network issues.

scp uses encryption to send both the password and the data. In this sense is far more secure. It also permits passwordless connection if you set-up a private/public key authentication (plenty of on-line documentation about this topic).
