If your priority is quiet, then Muscovy are definitely the way to go. We have (or have had) Cayuga, Welsh Harlequin, Silver Appleyard, and Muscovy--all reputed to be quiet breeds--but the Muscovy are BY FAR the quietest of the lot. We have found them to be smarter, friendlier, and more entertaining than the Mallard-derived breeds as well. You will not get as many eggs as you would with many other duck breeds, but they're fantastic at incubating and raising their own ducklings; and the eggs they do lay are large and rich. As an added bonus, they're wonderful for helping to control mosquitoes and other insects in your yard. They come in a wide variety of beautiful colors and patterns as well...blue, lavender, chocolate, ripple, pied, etc.
