I think you can get away with using both in a layered approach vs "all eggs in one basket".
- Nest Smokes/Thermos - these work well and eventually you don't have to futz with them all that much.
- Amazon Ring Products - Doorbells / floodlights are great, subscription plan is cheap and there is an upgrade path to the security system additional lighting. Google has cancelled their security system but their cameras are great, subscription can be expensive vs Amazon.
- Amazon Echos - They work well and the Echo Show integrates in with the Ring to show doorbell video etc - great for the babysitter.
I am a little leery about Google products.. sometimes Google just decides to cancel them leaving users hanging - see the "killed by google" site. I do have the older "Google Home Smart Speaker" that I stopped using because it wasn't as reliable as the echo. I'm sure newer models are better.
It seems that Google has the better tech but their strategic plan is a little less clear and seems to change frequently. This may be fine for Silicon Valley but for long term home integration it kinda sucks.
Edit: For the adventurous - have you checked out HomeBridge? This server can integrate both Google & Amazon products and send info to HE via the community Homebridge app or plugin. Even better no apple products required. It's just another way of connecting devices to HE. I use it for both Nest and Ring stuff.
