I did a similar survey walking mine and two neighboring marinas recently prior to buying our new anchor. Don't recall exact numbers but Danforth types made up roughly 75%. Purchased a Fortress FX-16 from Hopkins Carter and couldn't be happier with the results.
Call me ignorant but am a big fan of the idiom, when in Rome do as the Romans. Had I found a similar number of claw anchors I woulda went that route.
