I fire up my VPN software and ping all the servers, anything over 300ms is not interest.
To find a good server you either want to look for the best latency near you (but outside china) or the best latency near the target server (EU)

There are some hops the connection doesnt go over 215ms.. which is awesome.
Probably in game you'll get around 230ms to 250ms.
