Muscovies are simply... different. If you want duck eggs get Khaki Campbells, Welsh Harlequins or Silver Appleyards, all of which are good layers. If you want eggs, but also to eat surplus drakes, forget the Campbells, because they don't fatten up well.
If you just fancy having ducks about the place, stick to the call ducks, they eat less and are cute.
