I've flown both Singapore's A380's and more 787's than I can count. You're right, the A380 is very comfortable, but that's not 100% about the plane. It's about how the airline outfits the cabin.
I will grant you that the A380 is super duper crazy quiet compared with most other large jets. But legroom and lie-flat seats are available on all kinds of jumbo jets.
Except the Concorde. I had the privilege of flying that once. It was significantly smaller and less comfortable than I'd imagined it would be. But it made up for it in flight time.
Short flight with less comfort > Long flight with more comfort.
I can't imagine anything even approaching as small and uncomfortable as the Concorde. If anyone doesn't believe me, there's one at the Intrepid Museum.
I could barely board the thing and walk down an aisle, let alone try sitting in a seat. I can't imagine it being comfortable for anyone over 5'5".
