Yes indeed, "arguably" is the operative term. I would argue that the ATC services in, for example, FRA, AMS & ZRH are just as good (if not better) than LHR. Lets face facts, the UK is just slightly ah...."different" than the rest of Europe. When UK crews go to other locations they will just have to "go with the flow", or not go at all.
