Wireguard should leak less since the interface is up even if the connection is not established, it will still try routing packets through the Wireguard interface.

Not sure why Wireguard would be less useful in the mentioned countries, but I guess it is because of blocking of UDP traffic? And as far as I know, China and Russia does not block UDP traffic.

Wireguard seems to be something they can reliably fingerprint and block in Russia and China
