Ex-MS employee, Azure consultant here. I don't have any experience with AWS or GCP other than some very trivial, getting started stuff. But I really don't think what you say is true. While most of the stuff in Azure has a very familiar feel and intuitive interface (either on the UI or the API level) if you are coming from a MS background, there are still glaring exceptions and you certainly need experienced/certified people to build something that's ready for serious production usage. I agree though that Azure has a very nice and happy path for most enterprise cloud migration and hybrid cloud stories.
