I can only underline what the above posts state, definately go with the JAL option. JAL FA's are not "primarily onboard for your safety" .. 
and you are treated accordingly. Enjoy !</font>
I have to disagree. CX FA's are also used to providing a high level of service, and the crew even went so far as to recognize my AA status (greet by name, offer extras).
Nevertheless, sitting for 3-4 hours on a standard 747 coach seat is enough to make me wish for a 777 MRTC seat.
No matter how much nicer the FA's are, it won't make up for the difference in equipment.
