The CQR was at one time the standard anchor for an offshore cruiser. Compared to its competition at that time it stood out. But times change and at this time there are new generation anchors like the Rocna, its Manson copy, and others that do a better all around job. Anchors like the Fortress or Danforth are great as stern anchors but as many have experienced they often don't reset properly on a tide change.
Many experienced cruisers have not used a new generation anchor yet. While they may love their CQRs, without trying a Rocna or similar their statements aren't that valid.
As far as the new anchors being more expensive, price a Lewmar CQR. Copies are less expensive but never as good as the original. A modern anchor like a Rocna is competitive. And if you read their sizing recommendations you will also find that they need not be quite as heavy as some of their competition.
