On a 13 ton displacement ketch, with masses of windage and a long deep keel, I'll have my Danforth thanks. :-) (I think the Fortress is similar).
I think for ultimate holding on short scope, something like the Bruce is great, but I think setting them (in the smaller sizes anyway) is a bit iffy. They use them on oil rigs - or used to.
As with a CQR, a Bruce can be awkward to stow except over the bow. The Danforth stows well on deck, though its good at trapping fingers when handled.
