I use stone glacier although never had to haul out moose quarters on it, it packs a whole de-boned deer really well, is very comfortable just carrying my hunting gear around for the day. As mentioned above (Kifaru, Stone glacier, Exo mtn, seek outside, mchales, barneys ect.) are all top tier packs, it’s personal preference and how they fit to your body will be the deciding factor wether you think it’s worth it or not. For example If you spend $1000 on a stone glacier pack but it doesn’t fit your body or is uncomfortable to your body and you cant adjust it right to be comfortable then you will hate the frame/bag same goes with any top tier bags. It’s a shot in the dark because you cant go into the stores to try all these different bags out back to back or really load up the bag with weight in the store to get a feel on how the fit is.
Keep in mind most of these top tier bags are meat hauling capable the main bag will separate from the frame to strap your meat to the frame then you re-attach the bag and the meat sits in between the frame and bag, when your not carrying around meat it looks like a regular hunting bag. Also I know stone glacier you can ditch the bag say when you haul out the first load to camp you can ditch the bag section and just use the frame alone to haul the meat without needing to haul the bag section thus being able to drop more total weight.
