My Swedish is not so good, so I'm not entirely sure what's being tested in that Swedish test. I'm guessing it's the ratio of ultimate holding power to weight, in which the Fortress and other aluminum fluke anchors seem to generally take the top spot.
Personally I care very little about ultimate holding power, and a lot more about the anchor's ability to reset after a wind or tide shift. My aluminum fluke anchor fails miserably at that; I don't bother with it for anything except kedging and emergencies nowadays. Whenever I have the option, I go with my 22 lb. Claw. Never had it fail to set on the first try, and never broke out and failed to reset (and we have big tides here). Never dragged significantly, even in conditions when other boats ended up on the beach.
I have zero confidence that an aluminum fluke would do the same for me, after a small number of pretty astonishing failures.
