This is probably more true for long haul than short/regional. But good points also.
When I came I waited a little long to switch from BA to CX. In retrospect if I had been coming for a period that was definitely fixed at 2 years or less I would have stuck with BA. Anything longer and I reckon that, for all the reasons outlined here, switching to CX is the right move.
It also depends on the amount of travelling you are doing - for a few years I was (un)lucky enough to be able to maintain CX Diamond and AA EXP concurrently! Some Asia regional jobs have you on the road all the time.
