Just had the opportunity to compare business in CX and NZ, both flat bed products. My first time in CX with their flat-bed seating in herring-bone configuration.

NZ was excellent as usual.
The CX flight was overnight MEL-HKG. Beds quite narrow on CX compared with NZ. Felt like a sardine in a can. Not having to flip the seat over to get the bed on CX was not a bad idea, and I was able to raise the top half of the bed up a bit for comfort. (For NZ, I use 2 pillows to elevate my head) Bed felt a little bit harder on CX, but that could have just been me.
Wine list choices very limited on CX, food ok. I only had breakfast as the MEL departure was 1 AM.
Tray table quite small on CX, much prefer the larger table on NZ.
IFE was very quick on CX and I liked the IFE controller. It also displayed the time to destination which was handy.
Looking forward to seeing the new seating from NZ as discussed in other threads.
