1) Is it really worth going on CX if im in economy?

I'm planing on doing ADL-MEL-HKG-JFK and LHR-HKG-ADL on CX.

Is CX on economy as good on these routes as say QF or BA? Especially LHR-ADL and HKG to NA.

2) Which FF scheme would be best to join if doing ADL-MEL-HKG-JFK-MIA-POS-SJU-DFW-LAS-JFK-BGI-LON-HKG-ADL using AA in NA and CX everywhere else all on economy class?

Cheers.
