Pretty hard to go wrong with a Manson Supreme. The Rocna is an excellent performer but until they get their crap sorted out I would stay well clear.
The Spade is an excellent but very expensive anchor. I own two of them. I would still choose the Manson Supreme or a New Zealand or Canadian built Rocna over my Spade's every time. The three dimensional weighted tip of the Spade sets it back performance wise when trying to set in hard bottoms. Once set they stay set, re-set and hold very well.
The Oceanne, Sword or Raya were Alain Poirauds later attempts at competing with the Manson Supreme and Rocna. For years he bad mouthed the hoops on those anchors calling them BSH's or "big stupid hoops". After Alain passed away the company that now owns Spade came out with a "BSH" anchor...
I suspect Alain realized he needed an anchor with a one dimensional tip that could penetrate better in harder substrates, at a lower price point than the Spade but missed the mark with all three. None of them ever tested well or even came close to the performance of the Spade or a Rocna or Manson Supreme. As far as I know he never even submitted his last attempt, the Raya, for any independent testing.
The Manson and Rocna perform nearly identically and are tremendous performers compared to many older designs. They'll set in most anything but waist high eel grass or concrete..
