Tailscale somehow found use for self-hosters, despite being wildly unergonomic for an all-Linux, non-corporate, network. Yggdrasil lacks marketing effort, but is otherwise a great option.
I can't tell if you're being sarcastic, but assuming you're not: Tailscale makes security easier because networks are private by default. To achieve a similar effect with Yggdrasil you'd have to use a firewall to whitelist the Yggdrasil IPs of all your devices. So it's more work to set up.
