Because I sterted the discussion, I feel that I have to answer. I don't know which system is easier or harder. I can only say that I studied Pre-Primary education. It was a four year course (like almost all in Greece, except engeeneeering (5) and medicine (6)). For my degree I had to study 48 different modules and write a dissertation based on research.
I cannot say anything about the british undergaduate studies, as I have no experience.
But I have experience on postgraduate studies. I found that, during my first master, I knew a lot of things that british people did not know, BUT they knew how to do academic research work!
Now, my second master was a whole different thing as it was distance-learning. I can't make comparisons as I didn't meet anybody else.

Sorry for the mistakes. New keyboard!!!!!
