rintarou will fck all these koreans when hes high
just kidding, but yeah. we'd have to see. europeans would typically aim full on, or lead at 20 (a bit more skilled europeans, yes, you can lead 20 ping, oh my god, its so shocking.) eu (in this case) players would probably be a bit more mobile, however koreans could combat that on a no lead server, of if europeans played them in korea. Koreans would be used to 2 ping (regardless of where you live, you will be 2-5 ping in korea, even if you are on the other side of korea.)
i'll just vote for eu because i dont know, and we wont until its proven.
