My two boys and I all have the exo 3500 packs, and have been very happy with them, so far using them to pack out deer and elk . Great pocket layout and wonderful folks to deal with. Kifaru is another great one with lots of choices.

Can't go wrong with either.
I used Kifaru for years before they started actually adding some organization features like the current models. I decided to give Exo a try and I've been happy with it. (I don't/can't carry 100lb loads so no input there with either).
Although I try to drop my pack before any encounter, I shoot my bows (trad and compound) better with the Exo. Maybe due to narrower shoulder straps.
