If you can score the upper deck on the a380 it could it worth it for the cool factor and the 2-4-2 config. Otherwise, 787 is better is just about everyway except for seat width. The Boeing has a much better IFE screen, seats that arenโt worn out and armrests that go fully up.
I have to say the a380 seats are quite worn and the IFE is very very unresponsive. If you can score the upper deck though, you can get a window with storage bins that could be worth it.
