Podman has two main advantages over Docker:
* Does not require root privileges to run Docker containers
* Has no single running daemon as a single point of failure
And although it is compatible with running and creating Docker containers, it cannot use Watchtower for automated checking of updates for containers. But with systemd managed containers there is an auto-update option for Podman which is worth looking at.
