Keights[1] has a snapshot version available for running 1.14.0 in AWS, in case you can't wait for EKS :).
How does Keights compare to Kops ? https://github.com/kubernetes/kops
Kops is (intentionally) very out-of-date. This is a blog post about K8s 1.14 being released, but the latest stable Kops is still based on K8s 1.11.x.
Ah yes, OK. What about Kubespray ? https://github.com/kubernetes-sigs/kubespray
