As a cultural synthesizer ("create a sketch...") or translator (i.e., from human to programming) perplexity is as good as the others and maybe worse. But I like it as being an alternative semantic web search engine. Search engine because most of the time the facts are referenced at the end of the paragraphs and when it fails to insert them, I usually ask to expand. It's a new feeling after all those years of PageRank dominance. For example, It sometimes creates a paragraph with a reference to some recent research that according to the PageRank logic should be at the bottom (because almost nobody cites it). It's like the relevance was reborn. Once it was in a primitive sense of the early AltaVista, then Google killed it with PageRank, now when an engine really understands the question, the answers might become relevant in a new sense while being tangential to the reputations of the sources
