actually i am using both google nest mini and echo dot 3rd gen i feel alexa is far better than google if you want to choose a smart assistant just go for alexa unlike google assistant alexa understands better like people who dont know proper english can use the alexa it has good understanding skills but google assistant is not like that we need to say fluently to google assistant coming to voice recognition echo dot 3rd gen is better than google nest mini like it accepts voice from wide
