Do you plan to spend your career flying light twins or is it a step up to turboprops or jets? If it's the latter, then the DA42 is the most logical choice but if it´s the former, then find yourself an FTO with Senecas.
I can't see how, just because it has 'glass' and single faster-slower lever, a DA42 is any more step in the right direction for jets/tps than any other small aircraft. It seems to me to have none of the challenging aspects of neither jets nor traditional light GA aircraft.
Don't get me wrong, I would rather fly a DA42 than any other twin, but one's preparedness for type ratings is surely no better.
