Given most of the discussion so far is about which alternative is the best use of miles, then in terms of service I would say:
Food NZ > LX > BA
Wine NZ > BA > LX
Seat BA > NZ > LX
TV/Movie BA > NZ > LX
Lounge BA > NZ > LX
Service NZ > BA > LX
Overall BA > NZ > LX
In all above cases I'm referring to BA-F, NZ-C and LX-F class. That said I'd probably use the DC miles given the choice.
