I can only comment on the Stone Glacier, but I love mine. It retired my frame packs for sheep and goats. Way more comfortable to me.
I don't know the Kifaru packs at all, but I wouldn't hesitate to try them if I were starting over.
Pretty tough to argue with either one for a Dall hunt... Just look at your own sheep and the rams taken by Kurt Racicot while using the SGs... They're practically a lucky charm for big rams. grin...
