So you are saying that there is a Darknet, only that it is different from Tor network, which use is solely to maintain someone anonymous and all the benefits it brings?

That contradicts the comment I replied to, that is why I framed my question that way. I assumed I should consider Tor Network and Darknet one and only (as it is the top voted comment on HN, it gave me the credibility credentials to trust it with no second thought).
