Verdict
ArgoCD wins on user experience — its web UI is excellent for visualizing application state, sync status, and resource trees. Flux wins on the GitOps philosophy: it's pull-only, lighter weight, and integrates more naturally with Helm releases and Kustomize overlays as first-class CRDs. For teams that want visibility and a dashboard for multiple apps and environments, ArgoCD. For teams that prefer everything-as-code with no UI dependency and a lighter footprint, Flux v2. Both are CNCF graduated projects and production-ready.
