I'd say Google Assistant on Google Home is best. I own both Echo and Home and found Home to be the best at recognizing the questions and answering to my satisfaction. For example, I ask: "How much time it will take to go to Fifth & Mission Parking Garage by Car" and Home says "in current traffic, it will take you X mins." whereas Alexa concedes defeat by saying she does not know the answer to that. It seems to me that 5-10 years in future, Google will have a terrific Assitant that understands quite complex questions and will be way more helpful with the answers.
