I prefer the window in the SSIII, but experienced an uncomfortable sleep in seat 8A with the E91 configuration (first row of second cabin). Too much engine vibration which is something I never experienced in other 787 series seats (Seat 3A was fine on a recent trip) nor was it a problem with other first row second cabin suites like UA polaris (787 and 777). Might have had something to do with the way the seat is designed combined with the location near the wing mount and engine.
