Nothing specifically wrong with it. It is not an vital consideration (one of the best pilots I have recruited trained on the DA42 at Stapleford). The pilot's attitude to work is far more important, for example. Experience is the most important factor in recruitment.
However the presentation of information in the DA42 is different, and of course better. Thus when they get into my clockwork cockpit the person who trained in a clockwork cockpit, the hard way, is at a small advantage. Many pilots will also fly piston or turbo-prop aircraft and will have to cope with more levers than the DA42 has.
Remember, moving to a simpler aircraft is not a problem. Moving to a more complicated aircraft might be!
