I have an oversized Mantus anchor, same concept, and I sleep very well at anchor.
The "less hazzle" is really one of the biggest advantages in my opinion. We can sail for as long as we want, look at the map to find a nice place to drop anchor, and then it takes just some few minutes until we're set. No stress, can most often handle it very well alone without help.
Coming to some unknown harbour in the late night, not knowing if there will be space or not, perhaps having to do complex operations (like dropping the anchor at some exact place) perhaps in the darkness and perhaps while being deadly tired ... uff.
By anchor I can also get the anchor up quickly and without help and start sailing in the early morning while everyone is still sleeping. Leaving a harbour may be a more complex operation.
Of course, not all places are suitable for anchoring. West coast of Denmark for instance - few places to seek shelter except for in the harbours.
This summer we're trying to manage without the anchor as we have some problems with the anchoring equipment. We originally thought of going to Stockholm, but thought Amsterdam would be better when not having the anchoring gear working
it certainly makes a difference having equipment you are confident with.
