Right now, the folks at Stone Temple decided to make a detailed comparison video between Siri, Google Now and Cortana to see how they stack up when it comes to knowledge and their abilities to answer queries.
Here are their findings:
Google now was the best at showing “enhanced†results for queries. Enhanced results are results that contain snippets, images or other kinds of data that aim to answer your query without taking up much of your time. Siri came in second, with 29 percent of queries showing up enhanced results while Cortana came in last.
Google Now’s enhanced results were the best at successfully answering queries without the user having to go through additional links. Siri came in second and Cortana third.
