>The latter feels like a coherent setup with projects and IAM. AWS always has a surprisingly amount of work around org accounts and IAM setups.

AWS Organizations is atrocious compared to GCP projects. I truly do not understand how/why AWS is doubling down on the awful user experience of Organizations, cross-account access, creating multiple accounts, etc. It's truly the antithesis of customer obsession and yet they show no signs of moving away from that model. And not only is the user experience bad, it also just feels hacky. AWS Organizations and Control Tower feel like poorly applied band-aids rather than real solutions.

I actually prefer AWS to GCP in most respects, but the AWS Organizations shitshow is something I can't personally get over.
