OpenVPN is can hid your IP if set up correctly. Wireguard can in a way. But on the server your IP can be identified in some manner, maybe even after you sigh-out.

Wireguard is good for places like Europe and North America. But if in Mainland China, Russia, Iran and countries like that, you need use OpenVPN.

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
