The shorter barrel Hawken might be handier if you hunt heavy brush. Either one, with a 1:48 twist, will give the option of round ball or conical.
Both should be good rifles, and if they aren't Cabela's has great warranty service. I bought a .31 revolver from them a couple years ago and it wouldn't fire the caps (weak hammer spring?). I called them and had a replacement that works fine in only a few days.
