Kustomize is easier to manage at scale, but some upfront effort is required. Many charts are distributed as Helm packages, so you’ll often need to export them as raw YAML manifests. In an ideal setup, ArgoCD combined with Kustomize should cover most deployment needs. However, depending on your workflow, you may eventually need a way to dynamically replace variables. If the built-in tools in recent Kustomize versions aren’t sufficient, consider using envsubst as a fallback.
