I mostly day sail with the occasional overnight. I have used a Fortress for many years with 25 ft of chain and 250 ft of rope. Everything is one size over the recommended tackle for a 30 ft boat.
My next boat I might upgrade to a Rocna/Manson (one is crap the other is fantastic, can't remember one from the other lol).
The problem I have is watching the CQR, Delta, Bruce, Bullwaga, Rocna, Manson and who knows what sagas. Every time a new anchor comes out it's the greatest thing since the invention of the chrome pole until the next one comes out then it's absolute shite.
If you really do anchor in mud most of the time then I think the Fortress is for you. Unless you want to carry two styles of anchor (not a bad idea to have a second anchor).
edit: I should add that in my case, if I am not comfortable with the anchoring conditions I will rent a mooring or get a slip. I'm not cruising full time so it won't kill my budget.
