The camera feed is so slow since Google took over Nest, it barely works with the Google home app and keeps cutting out, doesn't load at all or keeps hanging sometimes. When someone rings the door bell then it takes forever to bring up the feed and let me talk to the person by the door. The Nest doorbell has become completely useless in its latest iteration combined with the Google home app. The person is long gone before I get to see who it was, which makes it really annoying and super unreliable to receive parcels when not at home.
I have never tried Alexa + Ring, but speaking to friends they are also getting more frustrated with the Amazon brand.
Is Apple a viable option today? If this stuff works well then it's worth having, but currently I wouldn't go for any smart gadgets and actively refuse anything from Google. I don't think they care about their hardware products. I've seen the same decline with their Pixel series.
