I went thru HPA over the summer. They gave us a choice as to who wanted the 200 vs 300 so we sorted it out amongst ourselves in the class. I was told by a friend to take the 300. Auto throttles and glass made it very easy. There's something with the 200 avionics where the two FD's can be showing different info at the same time and the AP still doing something else...I wanted no part of that mess and it was worth the extra 4 hours of differences training.
