I have travelled in F on a QF A380 two or three times. Each time it was part of a mixed QF and CX itinerary (AONE3s on each occasion). Each time I preferred QF over CX. I certainly am not trying to say that the conclusion you've reached is wrong, I'm simply pointing out that some (e.g., me and skunker) might find that the differences in service favor QF over CX, while for others (e.g., you) find that the differences in service favor CX over QF. In other words, there's some subjectivity to this analysis.
