Either is fine if leaving from Tokyo, but if coming IN to Tokyo, avoid NRT; trains are infrequent, slow (the only thing express about the Narita Express is the name) and expensive.
The F lounge in HND is better, but if you're after the flight experience (and won't sleep all the way through it) the 787 might be worth a try.
