Cloudhigh,
I trained with CTC. I was one of the two Kiwi guys they trained on the Wintec 2005/06 diploma course.
Having not trained with any other flight training organisation I can't speak on behalf of them but the training I received at CTC was very very good. But as with everything, it is what you make of it, eh? Some of the instructors I flew with in my time there were probably some of the best in NZ. One was ex-RAF fighter pilot, one has gone on to become an ASL examiner, others into Eagle.
The drawn-out radio calls are some of the british cadets trying to sound intellectual and professional... some of them tend to try too hard every now'n'then...
More info pm me if you wish.
