Avoid LH on the 380...even if you really want to fly on the 380, there are MUCH better options!
My order: AC, NH, way way down UA/CO and way further down: LH.
The soft product on UA/CO is dreadful with respect to the competition and LH's is horrible on the 380 - your service (and your girlfriend will think the same thing) will be more akin to economy service on the 380 - big carts, no personalisation, no real 'business' feel, aside from food on ceramics and a bigger screen - with the crummy angled/wedgie seats.
Good luck!
