To summarise, ANA First Class is the best experience I've ever had on a plane. The mixture of service, food and bedding is, in my mind, unbeatable.
On the ground the handling experience isn't as good as TG, the lounge isn't as good as the VS clubhouse and the service in OZ F blows every other airline away.
Despite all of this I wouldn't hesitate in picking NH F as the overall best experience.
