Hi Skystar
Yes, personally I would recommend the 733 over the 146 - the 146 F/As are all ex Ansett/QFNZ, and are probably still adapting to the NZ service/procedural ethics.
Also, the 146s are quite old compared to the 733 (10 years compared to 5 years for example) and are a bit less plushly furnished.
All the best
