my favorite elk pack is for my somewhat niche needs in a pack, and it's the mystery ranch pop up 18. most of my elk hunting is day tripping for roosies on the coast, and the pop up is custom tailored to that type of hunting.... love that little thing.
that being said, it's not what I would recommend for most people for a do all pack.
you cannot go wrong with kifaru, stone glacier, or mystery ranch, or EXO basically you need to decide on a general size, then look at features. stone glacier makes a beautiful lightweight pack, but I have no personal experience, but they are highly regarded.
Kifaru has a huge line for anyone's needs, and are probably the most popular. I have only packed 1 bull with a kifaru so I don't have a lot of experience on them either, but you can't go wrong with them.
I hunted an EXO 3500 one season, and loved it, light comfortable and well designed.... did good with a load, all around great pack.
I also hunted a kuiu for a season, and I like kuiu a lot, own lots of their gear, but imo, packs aren't their game, it was the biggest letdown of packs I have owned.
Mystery Ranch is my favorite packs, they aren't the lightest or heaviest, but they are TOUGH and well thought out. I would have no qualms buying any I mentioned besides kuiu, and I did get by with it for a season, not bashing them, but they are a lot of money vs their capability..... the rest mentioned are better in every way but weight.
seek outside is another notable brand, and build some good ultralight packs, but I again, have no experience with them.
there are some budget packs that will get you by, but are heavy and unrefined. I have a horn hunter full curl that's a workhorse, just kind of rudimentary compared to the high end packs. it hauls weight well, and mine has had a lot of heavy hard packs, and just a couple weeks ago i broke a buckle cinching down an elk quarter.... only failure on that pack and it's been beat up. they have a good warranty so no biggie
