OK, trying to keep out of the 'My ATC is better than yours debate', as lets face it there are a lot of parts of the world that could do with improvement, and the Dutch probably win the award for best ATC in a non native language.
I would be interested to hear from controllers who have worked in other countries - I know there is a Brit that works Toronto, and a Spaniard at LHR - what do they think is better/worse?
