Advantages of 'sudo' Over 'su'?

[Andrew Zbikowski]

Sudo adds a log entry of the command(s) run (In /var/log/auth.log). If
you mess up, you can always go back and see what commands were run.

I used to support a couple Linux servers on a consulting type basis.
The on site folks had sudo access. I always told them if you need to
do something as root, use sudo so there is a log of what you did just
incase something goes wrong and you need me to fix it. And if I see
that the command you ran was sudo su -, I'm going to charge double.

Or something like that.
