A little OT but I flew my first non-747 CW flight in a long time (LHR-LAX, 777-300) and really found the difference between aircraft noticeable. I prefer the upper deck, as do most people here, and a window seat for those bins at the side for extra surface space, but even a main deck window seat in Club on the 747 (I had 14A a few flights back) seems much roomier than the 777 window seat.
