I searched, but there doesn't seem to be a thread on NH's 787-8 184 seat business class seat.

Have the option to fly this aircraft NRT-SEA next month in a throne seat (8F). I'm familiar with business staggered on the 77W and 789, but it appears this is a different seat? And narrower? Should I stick with this flight, or should I be looking for something better (either 77W, 789, or UA Polaris?). Thanks.
