Yeah, but you don't need anything besides the runtime with kubernetes. Podman is completely unnecessary since kubelet does the container orchestration based on Kubernetes control plane. Running podman is like running docker, unnecessary attack surface for an API that is not used by anybody (in Kubernetes).
I run k0s at home, FWIW, tried k3s too :)
I can't really make an exhaustive comparison. I think k3s was a little too opinionated for my taste, with lots of rancher logic in it (paths, ingress, etc.). K0s was a little more "bare", and I had some trouble in the past with k3s with upgrading (encountered some error), while with k0s so far (about 2 years) I never had issues. k0s also has some ansible role that eases operations, I don't know if now also k3s does. Either way, they are quite similar overall so if one is working for you, rest assured you are not missing out.
