Runs on demand, doesn't require root, can be nested, usually uses newer and simpler primitives (e.g. a few nftables rules in Podman vs iptables spaghetti in Docker). In my experience it is ~90% compatible with Docker. The author explains the practical differences in the blog post https://www.edu4rdshl.dev/posts/from-docker-to-podman-full-m...
It is usually easier to install - most distros ship relatively recent version of Podman, while Docker is split between docker.io (ancient), docker-ce (free but non in repos) and docker-ee.
Not everything is rosy, some tools expect to be talking to real Docker and don't get fooled by `ln -s docker podman`. But it is almost there.

Regarding Debian, just `sudo apt install podman && podman run -it debian` - see https://wiki.debian.org/Podman
