I don't want to pass comment on who is better, however:
Why do the USA not adopt ICAO standards? They work. Nearly everybody else in the world does so with minor variations.
When I used to fly to the USA we were briefed on US RT and we would adhere to it, not just as a courtesy but as a legal and safety requirement.
Why do the Americans not do the same when flying into the rest of the world? Surely the US wide body guys and girls fly into the "rest of the world" often enough that learning the ICAO standard would be a requirement and easily achieved just by listening to what everybody else does.
