Podman vs Buildah: buildah from, run, and commit -versus- podman run, exec, and commit?

It seems we have the workflow to launch a container, and run commands inside of it, and commit it. buildah-from - Creates a new working container, either from scratch or using a specified image as a starting point. buildah-run - Run a command inside of the container. buildah-commit - Create an image from a working container. But we can do the same thing with podman? podman-run - Run a command in a new container podman-exec - Execute a command in a running container podman-commit - Create new image based on the changed container What's the difference between these two sequences of commands? When should we prefer one over the other?
