It's the usual question and answers again - I actually prefer the 777 as the cabin is much more spacious. However my 777 F flight had only 4 pax in total in the cabin, I was in 2K, and the 747 F flight I'm comparing with I was in 5E and it was full. So I can imagine that sitting in 2A or 2K on a 747 would be about the same for me as a 777 in 2A or 2K.
