Have not tried the others but CoffeeCup Site Designer is really good for fully responsive sites but it's nowhere as quick or easy at creating sites in as Xara. The great thing about Xara is being able to work with graphics and web layout in the same program. With CC and other tools you are usually split between working in a graphics program and the web program. But yeah I would recommend CC Site Designer too.
