AWS offers hundreds of very mature, extremely reliable services, many of which have either no competition or half-assed clones with few of the same features.

Serverless is a great example of this. GCP and Azure both have serverless offerings, but neither of them has the equivalent of Lambda Layers, which has been groundbreaking.

Even if we grant that Google's network is better, how can you point to that single dimension and claim that GCP is a better cloud platform? For most business's use cases it would be professional malpractice to recommend GCP over AWS or Azure.
