Google Assistant vs Amazon Alexa: which is the best intelligent assistant?

Google is adding functionality to allow Google Assistant to compete more directly with Amazon's Alexa, but what it really needs is to offer love and support to developers of smart home products. The company's failure to do this was visible on every stand where a smart home product was to be found at CES. They all worked with Amazon Alexa, but only a very tiny fraction worked with Google Assistant. Google's shopping functionality has involved linking the online ordering systems of retailers like Costco, PetSmart and Target with Google Home so it can offer a similar shopping experience to Amazon through the device. Measuring up to Amazon in this category is going to be tough because Amazon has one system through which millions of products are available globally, whereas Google will have to sign up lots of retailers in every locality where it aims to have this service available.
