My vote goes for the A380 if this is your first time, and if you like the wow factor...+1because it's new
otherwise the A319 for its cosy-ness, and the 777 ...which is also spacious. I really like the 777 2-2-2 config, much better than EK 2-3-2. I'd avoid the unrefurbished 330s and older 340s.
Armani kits were given out on my recent 787 BRU and 330 KUL flights last week. Until 2 weeks back there were Ferragamo. Either new stock or extras from A380... Sometimes hard to tell with QR...I've had Dior kits last year on my 777 to IAH!
