I don't work for EK but my sister does.
A380 means less destinations but more days off. Good destinations and usually long-haul flights.
Personally I would like to be on main fleet first so I can see more destinations. Then maybe join A380 later when I've seen most places.
It's a personal choice I guess. A380s are the premiere aircraft so it would sound impressive when you say you work as Emirates A380 cabin crew.
I'm sure the current CC can add more info
