Have not flown the DA42
But I did sit in one a couple of times (cockpit familiarity) and I have some g1000 time (over 100 hours). I have instructed in a Seneca, Aztec, C310, Navajo, and Baron, and got my Multi in a Duchess. I have also flown a Twin Comanche, King Air 100 and 200, and a Twin Otter. Far and away, the best for training was the Duchess, and my favorite from a pilots perspective is the Baron 58.
