I have a kifaru and a stone glacier. Both have held up well, I haven’t had anything really break on either of my packs. My kifaru has the tactical frame so it’s pretty beefy, I’ve hauled out moose quarters with it, dealt with swamps and alders and it’s done just fine, it does have a lot of straps though.
My stone glacier had been on 4 mountain hunts of 5-10 days at this point, I think it actually shows more wear.
I like both, they both have fairly specific uses for me so I don’t know that I’d want to pick one over the other.
