"Best" is not a concept that has any meaning at all, when you're talking about objects of unlike kinds. Which is "best", a tractor or a trawler? It very much depends on what you're trying to drag. Which is "best", a minnow or an upholstery tack? Again, it depends on what you're trying to nail.
So, two websites from two different businesses cannot be compared. If you want to know all about Ace Hardware, the Acme Tool Company website is totally useless, regardless of its beautiful graphics and logical navigation. For you, the Ace Hardware website is the _only_ website that matters, and the Acme site is irrelevant. So which is best for the purpose? There's only one site that has one purpose, and it's best for its purpose. And there's only one site that has the other purpose, and it's best for ITS purpose. And they both get listed, in any order that happens to be convenient.
Because that's what the ODP lists. Unique content. Websites that don't ever get compared to the competition because there cannot possibly BE any competition for them. (The businesses may compete, but the websites do not and cannot--they serve completely different purposes.)
