Maybe it was ten years ago. Not any more, no better than any airline that has flat bed seating in business.

It will help if you tell us where you are departing from and whether you are OK with making one stop on your way to Europe. For example, there is a complex scheme whereby Amex miles can be used to go via Air New Zealand, believe it or not, from LAX to LHR. Their business class beats any of those you have listed but obviously only makes sense if you are going from the west coast. There is also Singapore airlines from JFK to FRA, but that's harder to get on an award.
