Everybody is different, right? Same with Alexa and Siri. Siri is smarter than Alexa, mostly because Siri has a "blackboard" to write on, too, and Alexa can only talk, as Parker said. If I really want an answer I ask Siri, if I "hope" I get an answer, I will ask Alexa first. And if I really, really, want an answer, I get on the computer and use Google.
