Zerotier works at a lower level. This means you can do other protocols than tcp/...

I don't think that's correct, they both expose TUN/TAP devices so should be equivalent in their encapsulation abilities. I use both regularly.

It is correct because a TUN interface is not the same as a TAP interface. The latter is layer 2.

Tailscale can do UDP also.

"TCP/IP" means TCP, IP, and UDP.

ZeroTier can do other protocols like NetBIOS, so you can use it to run LAN games that don't use TCP/IP.
