ELI5: Where did the "S" rating originate and why is it better than "A+"?

I've searched on google to no avail.

It originates in Japan, the land of all the crazy things. Because it's known that if you get less than a C you have failed there would only be 3 grades you could get if you finished a level (as they often did not have +- modifiers), S class was introduce something difficult to give people a sense of achievement and something to work towards getting. Then came the SS and SSS ranks to create even more grades to get because more letters clearly means it's better.
