Portugal/Brazil deserve major
You really asking? Katowice...
Can't judge till we haven't seen some other cities, but I'd go with Cologne or Kato
Cologne and Katowice both have the best crowd!
(Remind of many people gonna fly/drive to each event in the different country to visit these both)
imo theres no other event who can beat it
katowice for sure. but cologne was pretty good.
