Amazon EKS vs Azure Kubernetes Service

Three of fourteen models named Amazon EKS first on the direct prompt; three named Azure Kubernetes Service. Both were named by all fourteen models and both carry 71 labels, so the shares below are directly comparable.

The direct prompt

The plain question, one answer per model, grouped by where Amazon EKS and Azure Kubernetes Service stood in it.

Both were the first choice

1 of 14 modelsThe answer named them together, and the judge labeled each a first choice.
