I've used all 3 major providers, and I am going to have to strongly disagree. Out of UI, Azure is far and above superior with AWS and GCS which are both confusing messes. That is literally the worst complaint I can even think of in regards to Azure.
Further you can use Powershell (from the UI, no less,) if you are all about CLI.
But every time I deploy a new AKS services, it takes 30 min for it to be ready. I luckily haven't had to do this recently (~4 months?) and I'm loathe to try again. GKE on the other hand is within 2 minutes.
