Which of these "Spout Touring" bikes is the best?

Goldwing does not a sport tourer make. For Honda your'e going to be looking at the ST1300 not the GW. Also If You're looking into Sport Tourers like I am don't forget the Kawasaki Concourse 14. Bottom line the only way to decide on a bike is to go around to dealers and sit on each one you are considering. You can get all the advice in the world, but just sitting on the bike itself will tell you a lot more.
