Siri, Alexa and Other Virtual Assistants Put to the Test - The New York Times

Results from a test with 16 common tasks

"In the end, none of the voice assistants earned a report card that would make a strict parent proud. Here’s how they stacked up in terms of grade-point averages out of 4.0.

• Google’s Google — 3.1
• Apple’s Siri — 2.9
• Microsoft’s Cortana — 2.3
• Amazon’s Alexa — 1.7

Apple was the strongest at productivity tasks like calendar appointments and email; Google was the best at travel and commute-related tasks. Alexa excelled at music, and Cortana was mediocre across the board. Facebook was left out of the grading system because the company denied access to M, though I did hang out with her for two hours on a friend’s account. More on that later."
