I've used the Timberline 1 extensively along with a about almost every Kifaru pack. My go to for extended trips is still the Timberline 1. The AMR is awesome, but has only those two front pockets for external gear organization. I like the Timberline 1's side pockets for easy access to Rain Gear etc.
All this being said some of my friends absolutely love their AMR, and wouldn't switch for anything.
I've packed half an elk whole mule deer, and all of camp in my Timberline 1 multiple times. Pack loads exceeding 190 pounds, and down to 25 pounds for day hunting. Unless your packing bear hides or moose quarters I'm going to stick with recommending the DT1.
If your a bear hide, moose quater, and pack raft ninja then I'd say EMR II all day every day.
