It doesn't take much legwork to find counterexamples of that claim, even on HN (see below, I spent 2 minutes searching to find those).
> Google's customer service is the worst I've experienced in the industry (like even speaking to a person is hard). While AWS is some of the best I've received.
This is a bit too hyperbolic for me, but on balance I agree that Amazon has better customer experience than Google. That doesn't really answer what GP is asking, especially given all the posts made about AWS on this very forum that only sometimes get attention.
