Besides fuel efficiency, what are the advantages (for the passenger) of flying on the Boeing 777 versus the?

Joe.R asked:

747? I know that the 747 is wider than any other twin engine aircraft (which are so in vogue today). That is definitely NOT an advantage for the passenger, no matter how you look at it.
Maybe there are some other advantages that I have not thought of? Are the seats typically more spacious? The aisles wider? Bigger bathrooms? Quieter or smoother ride?
Or is the current trend to use smaller twin-engine aircraft bad for the consumer in almost every way?
