Yes, the 380 is without question the most comfortable and quiet beast I've flown on.
I love the T7 too though, even with the famous figure of eight wobble felt in the rearmost part of the cabin.
The difference became obvious on a few trips to Vietnam - first leg from London to Dubai on A380, second leg to Saigon, T7. The returns were a treat though, knowing that you had the smooth comfort of the 380 for the last leg home. Ugly sod it might be, but I'm on the inside enjoying the ride, not outside looking at it.
