Honestly, Koreo can cover most of the use cases of the other tools just fine. We leverage Koreo to manage deployments of the Koreo controllers along with their service accounts and RBAC—it works quite well. We also use it with Helm in order to install, for example, ACK controllers which have existing Helm Charts.

Our design is very, very deeply inspired by Kustomize. If Kustomize or kpt are sufficient, I would strongly encourage using one of them. We developed Koreo because we have cases where we need to sequence resource creation (for instance to map values from one resource to another) and wanted to programmatically set values.
