I'd look at schedule/arrival time/price first as the primary decision factors. If those are all quite similar, personally I would go for the A380 as I find it a far easier plane to sleep on (777's tend to make quite a racket), and despite it's detractors, I find CW more comfortable as a bed over the Collins Aerospace seat on the AA options.
