* Cilium (v1.8) was added to Typhoon in v1.18.5 in June 2020 and its become more impressive since then. Its currently the leading CNI provider choice. * Calico has grown complex, has lots of CRDs, masks its management complexity with an operator (which we won't use), doesn't provide multi-arch images, and hasn't been compatible with Kubernetes v1.23 (with ipvs) for several releases. * Both have CNCF conformance quirks (flannel used for conformance), but that's not the main factor in choosing the default
