In practice I find it stupidly reliable, and use it to reconfigure/fix WireGuard issues remotely (I had to fix the MTU once on hotel Wi-Fi).

It's also completely open source, unlike tailscale. And something's that cool is that Yggdrasil can automatically peer over "unconfigured" layer 2 links so if you have a complex topology (like an actual mesh) it can be useful for that.

It's also stupidly simple to set up Yggdrasil in a dual WAN environment, which is nice.
