Worst, perhaps. However, in terms of "worn out" the 777 currently has the oldest J cabin in the fleet (though updates are about to start), followed by the 767-400, then 767-300, then A330, then 757, then A350. I believe it would be the 767-300 on this route which was last updated about 8 years ago.
