A 250 cadet in Europe is far a different pilot from that of a 250 hour pilot in the States.
Every one of those 250 hours a cadet accumulates is structured. Structure means discipline... perhaps because of the costs involved, or the course itself.
The academics and testing a cadet completes is far greater in scope than that of a 250 pilot in the US. Is a cadet a better pilot than a 250 hour pilot from the States??? or is a 250 pilot a better pilot than a cadet. They both have their merits.
But at the end of the day... it's the guy in the left seat that will set the tone how the flight will be conducted.
Both pilots have an acceptable expectation that both shall follow the conduct themselves as if a check ride were in process.
