Wow...good question.
I prefer Galloway, but it is difficult and it can be a long day if you're off your game.
Hidden Creek is much gentler, but more of a subtle challenge and a real nice "look" and feel to the place.
Atlantic City has a terrific front nine, but that back was affected with the decision to create a new "practice grounds", which limited the options and thus impacted the routing adversely, IMHO.
