I'd personally disagree. I pax on emirates a lot positioning to start rotations. And I deliberately choose where possible A380 flights.
The business class offering is fantastic. If it's an afternoon flight I enjoy the craic at the bar. If I'm tired I can have a good sleep without being stepped over/having to step over. If the person next to me has an unpleasant odour I have plenty of space. All attributes the 777 doesn't have.
My experience from chatting to fellow pax indicates I'm not alone.
Now if only they would de plane the top deck first........
