I agree with Fuji, Make sure that you know your checks inside out (but then that goes for all aircraft) coz its an expensive place to make mistakes and learn stuff that you should know on the ground...
As one who's flown Seminoles as well I preferred the Seneca it has more power but then that also contributed to problems getting used to the throttle controls...they are very sensitive and you have to take into account the lag on the Turbo but overall you'll enjoy the seneca. She's not as bad as the seminole SE and has a better SE climb rate but you may have to drop the power on the good engine to make sure you can maintain lateral direction control.
BBut as long as you keep the MAP below 40 you're grand...
Enjoy!!
