Warning: The following contains opinions held by the author and do not necessarily represent the opinions of everyone on this forum. 😱 (After all, it is about anchors.)
As to voting, I'd go with a 14# Delta@, which we have done on our R21.
We carried a 35# CQR@ and a 44# Bruce on our Crealock 37, and both were outstanding. The Bruce was primarily our storm anchor or became the bow anchor against the strongest tidal flow or wind if we had to use a "Bahamian Moor" for some reason.
The only place we had trouble with the Bruce was in heavy grass over sand in The Bahamas. The flukes would gather grass as they tried to set and then become nothing but a blob. The side flukes would not do the rolling action that they are designed to do to make the primary fluke dig in. That was not a show-stopper since we always dove on our anchor to check the set. If I needed the added holding of the Bruce I would just start the set manually. In any other bottom it would set like a charm. The CQR would set in everything. The point would slip through the grass and get to the sand without loading up the plow with grass.
We carried a 55# Delta on our Atlantic 44 and it set every time and held well. The Delta is a close relative of the CQR, primarily lacking the swivel joint. It does seem to turn in the bottom quite well when it needs to. So while the swivel joint may facilitate that a bit, the Delta seems to do just fine without it. (As does the Bruce.)
We also carried a couple of Danforth@s on the Atlantic which were on board when we bought it but only used the lighter of them in non-critical situations as off the stern to keep it out of the fairway when anchored on the river systems. The other one was a real brute that had been the previous owner's primary anchor. We kept it to use as an anchor of last resort if a super-storm was coming but we never had reason to set it. I do not generally recommend the Danforth for a primary anchor since they do not turn well. A trip around most large marinas will turn up a pile of Danforth-style anchors with bent shanks. Another problem is that they will sometimes break out and not reset. That happens when the wind or tidal current go slack and reverse slowly and rebuild. The rode can either tangle on the rods on the flukes or just get directly over the anchor and when the strain increases the anchor will flip out of the bottom. I have seen it happen, so this is not just hearsay. I still like the Danforth because of its superior holding for the amount of dead-weight, but I would not sleep on one, especially in water with fast tidal flows or under changing wind conditions.
If I had only one anchor rode and anchored on anything but rock I would (and do) use a Delta. If I were sometimes going to have to anchor in rock I would go with a Bruce. With two rodes I would carry one of each.
