Please, take a look of the 🎥 video from the DevOps Toolkit YouYube channel. In the video you can find comparison between four k8s providers, EKS, AKS, GKE and Linode.

Amazing series of blogs for EKS proffesionals https://learn.microsoft.com/en-us/azure/architecture/aws-professional/eks-to-aks/
Really good blog about storage performance with Azure Kubernetes Cluster, File Storage and Disk, but probably the same concpet may be applied on the EKS. Take a shoot https://www.feval.ca/posts/k8s-io/.
At the moment, there is no better blog, test, or whatever on the Internet about containers and scale performance then https://www.vladionescu.me/. You need 4️⃣5️⃣ minutes to walk trought the post. https://www.vladionescu.me/posts/scaling-containers-on-aws-in-2022/ Enjoy!
I believe that AKS has better integration with developer tools, at first with Visual Studio Code and Visual Studio. Yes, they are Microsoft's tools and it is something expected. You can deploy a container to a cluster from IDE. From oposite side, it is not something that AWS doesn't want in the eco-system but it's not primary focus. Still, it is maintainable at the both cases, anyway you should use CI/CD concept and tools.
