The best of the best
In addition to me being an IT professional and owning both the Amazon Echo Dot (which I LOVE) and the Google Home Mini, I have found myself recommending the Google Home Mini (GHM) to friends and family.
What makes the GHM better in my opinion is the fact it integrated with the Google ecosystem which includes YouTube and Google Music. The main things that you find yourself asking these devices are search engine related questions like commute times, weather, recipes, and random trivia. The GHM is integrated into the Google ecosystem which provides the best lookup support and has about a ten year head start on the competition when it comes to voice recognition.
It also, unlike the Echo, retains the context of your query in case you want to ask a follow up question on the same topic.
