747. Any time of the day.
Just arrived in Barbados yesterday on a 777 yesterday (my first 777 flight, actually as I've always been flying on 747's) - and I may be colored by the fact that the IFE system was ancient, but I prefer the 747 - more intimate and as several have pointed out - its a cul-de-sac with no through traffic.
But for the love of everything holy, please roll out the updated F - getting in a plane with a IFE from the 90's is just *facepalm*. But thats somewhat off topic (although I haven't seen that system in 747's since the 90's or so).
