Alexa vs. Siri vs. Google Assistant: Which Smart Assistant Wins?

Our overall winner in the category was, perhaps unsurprisingly, Google Assistant. It answered more questions correctly than either Siri or Alexa, as well as generally giving context and often citing a source website for the information. Given that it's backed by Google's powerful search technology, that's to be expected. It fell down only on a couple of questions: It couldn't tell me when the next episode of Arrow aired (though it could interpret that as a TV listing); it gave me departure time for an upcoming flight even though I asked for the arrival time; and in a question about the American League Championship Series, it gave me recent scores, but not the overall standing of the series. However, it was the only one that could tell me how long chicken stays good in the fridge; gave me detailed information about the distance to Jupiter; and correctly identified what most scholars believe to be Shakespeare's first play.
