1.) modern
2.) more tech stuff to play around with
3.) Steel Beasts Pro (now that is a surprise, isn't it
). Why? Simple: it is by a great lead the best there is in the field, and even compares to the best sims available in general in all genres, surpassing most of them. That's becasue it was designed not with the gaming market in mind, but for the pros, and was designed by people knowing the stuff inside out from reality.
