GCP is behind. They're are behind in niche services to be fair but behind nonetheless. Nothing that prevents building similar services, but coming from AWS, I routinely feel frustrated by lack of finesse and comparable offerings. IMO, GCP's greatest benefits over AWS are:
* BigQuery
* Tighter k8s integration with GKE
* Single message service (PubSub)
Unless BigQuery is your first class citizen, I would avoid GCP.
