Whenever I've needed AWS support it was just as aweful as GCP. For example, 12 hour Aurora outage, support was only replying a generic "waiting for engineering team" answer, SLA only refund about $15 although we ended up paying for all the replicas we tried to spin up from backups and wouldn't start. Architect and account manager didn't give a damn about our issue.

The way to get good support from AWS and Google is the same: find someone on your team who is ex-[AMZN|GOOG] and get them to email their buds.

Or, if you purchase consulting hours from any of the major firms, get ahold of their sales team and have them run the ladder for you. A GTM partner is generally more than happy to leverage their firm's relationship with the public cloud providers in the service of their relationship with you.

Not sure that paying for support is even that helpful. I was responsible for a few tens of millions of dollars in client GCP spend (admittedly, a small fraction of client AWS and Azure spend), and I only spoke to any official GCP reps once -- and they were from a recent acquisition. Our GCP team had closer contacts, of course, but as far as my experience went Google compared unfavorably to both AWS and Microsoft, who were happy to throw SMEs at me anytime I had a question. (Even so, there's a lot I do like about GCP, even if I'm a bit uncomfortable with its long-term prospects.)
