I really dislike the Google Cloud way of doing things, for example Projects, Folders and Orgs. There's a dozen different weird paradigms that you have to consider to securely and reliably manage a large number of different projects, accounts, tenants, business units, etc in Google Cloud; if you don't do things "The Google Cloud Way" you are screwed.
AWS is much simpler and more straightforward. You don't have to think about anything to segregate infrastructure, networks, applications, users, data, etc. Just put it in a different account. If someone needs access, you need to explicitly add extra connections/grant that access. You can't just accidentally create one user that implicitly has access to hundreds of accounts.
Honestly the entire security model of Google Cloud is frightening. It's like they wanted to make it easy to expose everything.
