Using $_GET

That's a terrific tutorial but the one thing it doesn't do is explain why you should use it instead of your own way.

It complies with vBulletin's coding standards, I don't know why you wouldn't want to use a tool like that provided for you. If you are going to run the sanitizing functions manually, it is fine, but it is always open to you forgetting to clean a variable. If you use $vbulletin->GPC, you have more confidence that your variables are being cleansed properly.
