I have had more than one of both, and I don't think a fine frog hair would fit in the differences, as far as build quality and/or strength is concerned. Both are, in my opinion, very good examples of American style SxSs. I have more rounds thru BSSs, but I never had a hint of an issue with either one, and I also killed quite a few waterfowl with as heavy a loads as I could buy or build.
