While both k3s and k0s are designed to be lightweight, k0s has several advantages over k3s. if K0s is actually better/faster/easier. Correct, the component that allowed Docker to be used as a container runtime was removed from 1. The target would be 200MB or lower. EKS is easier to do a container assume role. Defaults are fine for a typical micro lab cluster. nothing free comes to mind. But if you need a multi-node dev cluster I suggest Kind as it is faster.

So now I'm wondering if in production I should bother going for a vanilla k8s cluster or if I can easily simplify everything with k0s/k3s and what could be Why do you say "k3s is not for production"? From the site: K3s is a highly available, certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances I'd happily run it in production (there are also commercial managed k3s clusters out there). There's also a lot of management tools available (Kubectl, Rancher, Portainer, K9s, Lens, etc. So here is what I recommend you do Take 1 host, and install docker, and spin up some containers.

I use k3s with kube-vip and cilium (replacing kube-proxy, thats why I need kube-vip) and metallb (will be replaced once kube-vip can handle externalTrafficPolicy: local better or supports the proxy protocol) and nginx-ingress (nginx-ingress is the one i want to replace, but at the moment I know most of the stuff of it). On k3s you are forced to do that, that's why it's recommended to set --node-taint k3s-controlplane=true:NoExecute on the master in order to avoid running pods on the control plane server. K3s is a distribution of kubernetes that’s easy to install and self-manage with lower resource use than other distros (making it great for raspberry pi clusters and other edge/embedded environments).
