There are a lot of technical refinements in GCP that makes life a lot easier than AWS, but nothing strategically compelling enough for the cost (in cash, developer time, and burning relationships) to jump ship. So I make-do with the not-as-great technology. They are pain-points but not deal-breakers.
I think if our startup were doing AI/ML, or even heavy data processing as our core technology, there's probably enough compelling reasons to invest in a move to GCP. But it isn't.
If I were greenfielding a new launch at a new startup, I'd push for GCP.
I have never worked for Google or Amazon.
Disclosure: ex-googler (left 4 years ago), own no GOOG, use GCP to run my own business. Clients use whatever they want.
AWS is just another IT vendor. The weird dependency, reminiscent of 1980s IBM thinking, is bad for any company, at some point you become more of a vassal than a customer.
I somehow got CC'd to an internal Google system, Buganizer, which has done nothing but leak a bunch of internal communications, including some small code patches to GCP infrastructure itself.
My support request has not been updated, but Buganizer has let me know that they supposedly updated the documentation mid-November to fix it, but the rephrased advice still was not correct based on my interpretation of the issue. The bug is still open.
But, I have always enjoyed using public GCP more that AWS.
I see a proliferation of AWS services, yes, but many seem to be replicating things that GCP has had since the start, in multiple different formats without clear direction. Bigquery covers most of the use cases of Redshift, Kineseis, Athena, EMR, and others. It is at once decoupled from and well integrated with their object storage, allowing reads and writes with clear translation when necessary. I find myself reaching for Bigquery like semantics all the time and having to cobble two or more AWS tools to get similar. I see the same pattern repeated constantly - If I click "ECS" in the Amazon Console, it wants to sell me ECS, ECR, Fargate, and EKS - All of which overlap in non-obvious ways.
