As noted, humans really really like rankings. I think it feeds our ego (or diminishes it, in which case we probably claim the rankings are bogus).
Take any such ranking, wines, cheese, food of any type, restaurants, best places to visit in Europe/Asia/Antarctica, and "we" will check out where we're been or dined or drunk against the list, and then probably claim the list is bogus.
Or brag that we've actually sampled from wine of X type. Or brag that OUR team is in the Top Ten (yay).
I think there can be some merit in such rankings at times, but for the most part, they really really are irrelevant to the vast majority of us.
