It's marginal IMO. I have a slight preference for the CX 744 F environment over the Airbus, but the service is identical. One thing to bear in mind is that Chinese New Year next year falls on 9 February which means that flights in the region may be a little harder to get for a week either side. Note also that in HK and Singapore some places are shut (for one day at least) and it is very much a family time; it can also be harder / more expensive to get hotels. However, you would get to see the fireworks if you are in HK on the evening of (I think) 10 February.

(I guess there is also a smaller CNY celebration in Sydney, but you might have to hunt it out)
