Can't speak about Google but I've been using Ubiquiti Unifi for several years now. They have a home version available but I opted for the enterprise grade stuff. Each access point is about $100 so you can start small and add on. I bought a 3 pack and it's a bit excessive for a 2000 sqft house. Could've probably done with 2.
https://www.plumewifi.com/ is another option if you don't want to mount Cisco size frisbees everywhere.
Another thing with Google is if they lose interest in the product, they'll ditch it... Google Glass, Nexus Q, etc...
