Docker, or rather containerd, still has better plugin ecosystem around it. Unregistry https://github.com/psviderski/unregistry, Nydus https://github.com/dragonflyoss/nydus, all the different "snapshotters" (storage formats), or the utils for sharing NVIDIA GPUs with containers, etc.

The gap with Podman is closing though, and most users don't need any of these in the first place.
