k8s is basically a standard interface for cloud providers, where you can define load balancers, persistent volumes, certificates, etc. in addition to jobs and services. It has a well thought out declarative language that maps well to how ops runs things at scale.

There are quite a few optional tools built on the k8s model, like service meshes or tools to orchestrate a postgres cluster.

Swarm is a small piece of that, the scheduling system, and you have to run it yourself. It's really not comparable.
