Suid scripts are considered more dangerous than suid binaries because,
historically, many scripts have been interpreted by /bin/sh (i.e. bad
code), and thus their meanings depend on the values of environment
variables such as IFS and PATH.

sudo has the advantage over su that, if you learn how to configure it
properly, you can allow certain users to run certain commands without
typing the root password.
