Also, NEX being much faster than a taxi is nonsense. Door-to-door taking a taxi is much faster even in traffic. You have to factor in getting down to the train, buying a ticket for a train that runs every 30 minutes and then getting from the station to your ultimate destination. A cab is faster even if you stay at Tokyo Station Hotel. You also get to see more, especially if you go via the Rainbow Bridge.
Before Xmas it took me one hour and ten minutes by car to get to NRT from Shibuya station area. And then the 3 was bumper to bumper all the way from Shibuya on-ramp up to Shiba-koen. Then NEX train takes 80 minutes to cover this journey plus I have add to 30 minutes to comfortably get from my house to the train.
But NEX is definitely cheaper for 4 people because the net cost is only 6000 yen if you do the NEX/Suica deal.
It's funny how people factor in buying a ticket and waiting for train, but apparently the taxi meets them at the carousel. The reason I said NEX or Skyliner is the departure times are staggered, there's no point in taking one if you're going to wait 30 minutes. If you wait for 30 minutes you might as well take a limited express with the closer departure time.
Not sure why it's "rubbish" to you. Tokyo station is 50 minutes by NEX, more then 60% faster then you think, and Ueno is 42 minutes by Skyliner. With transfers it takes less then 60 minutes to get to any major station.
70 minutes from Shibuya is impressive and I would consider rare since its normally a 90+ minute ride.
Up to you really, you'll get wherever you're going in 60-90 minutes, if you're willing to burn a few extra dollars for the familiarity of a cab you're not alone, follow the line of tourists.
