I like GCP as well, having previously used AWS for many years.

The biggest issue is that it's taken Google a long time to figure out what enterprise security is - it's not something what was in their DNA - and the product shows it. They're too focused on weird fancy half-assed "beyond" solutions to properly implement the basics. They dangle clever federated etc. solutions that only work in some circumstances so that you're better off just avoiding them, but the more basic alternatives are limited in their own way because they focus too much on the fancier solutions.
