I think the point is being missed entirely here; willy-waving about whose airport is better on which side of the pond is a boring side-track. As is debating regional differences such as "director call sign only". Even in the UK alone there are a myriad of different ways to skin the cat, whether it's Southampton insisting that we read back "next frequency when instructed Solent 120.225" with the clearance every single day (WTF indeed) or East Midlands wanting us to squawk ident on the approach frequency.
The important point is using standard phraseology spoken in a clear and concise way. This applies to all of us. Understanding that not everyone has the same command of the English language that you do, or do not have ears tuned to your accent, would go a long way to making sure all the players involved are aware of what is expected of them. It isn't just beneficial for the controller and immediate recipient, it aids the situational awareness of all other traffic on the frequency. It might just be the last line of defence in preventing someone lining up without clearance with another on a takeoff roll, for example.
