What is the benefit of sudo over su

I have this (stupid) question.

What is the actual benefit that ubuntu (or debian derivatives) achieve by disabling root user.

Everywhere I read, its says to prevent unintentional damages for inexperienced users.
I want to know what exactly. Since sudo can execute all commands (that I know/ use). So in what case root can cause damage whereas sudo can't?

PS: I know how sudo works.
