Do you consider the "960 Grid System" one of the "Holy Grails" of User Experience layouts? [closed]

Is there a "Holy Grail" of layout?

I recently redesigned a website for a client (University of Connecticut Coop), where I happened upon a link in their old code to this article: "http://www.alistapart.com/articles/holygrail".

Upon researching further, I also came across the "960 Grid System": "http://960.gs/demo.html"

I then began to wonder..."Am I missing something here? Is there a consensus among design professionals regarding the best User Experience for layouts?"

So, I put it to you: "Is there a "Holy Grail" of layout?"
