My first Amazon echo was the Amazon Echo Dot, which is a smaller version of the full "Echo" device.
While the Dot is a great, device, the sound quality is a huge improvement on the full Echo. At the time, I considered both the Echo and the Google Assistant. I found the Echo had better support, apps, and less restrictions if I wanted to make my own apps (although this has changed and it has locked down as well).
The Google Assistant is getting better, but as a big Amazon user, it seemed like the better pick. Believe it or not, I never actually ordered anything from the Amazon echo even though that's one of the most touted features. Strangely enough I use it mostly for listening to music when I don't want to wear headphones.
I do like the flash briefing feature where I can pick what news apps I want to subscribe to and it will let me ask for a quick update on a daily basis. There are stock, world, crypto, and even tech news.
Want some laughs? This video is funny, some guy got the Alexa, Google Assistant, and Siri to talk in circles automatically.

The Amazon echo is available for $95 on Amazon but sometimes can be found bundled with other gadgets during holidays.
