You can mix ecosystems pretty easily with Zwave, smartthings, and IFTTT. Those combined with Google assistant are awesome. Take it one step further with Home assistant and you are automating everything AND not having the online requirementsAll these products come down to ecosystem...I have Chromecast...YouTube TV...Chromecast Audio...Google Play...Hue lights...works well with them and also functions as my alarm along with other utilities
I prefer it over the Echo because the Google Assistant can understand mostly plain language as opposed to explicit commands so itβs more natural to use.
Echo beats it in terms of ordering from Amazon but Google has partnered with Walmart and other places to round out the ordering features.
