Along_the_Wire for me leg room important for long haul, as I genuinely stick my headphones in and listen to music for most of it, so not fussed about noise and any other comforts.
Would stay clear of AA as we had a shocker on the way back from Vegas a few years back. Thought we were on BA but it was an AA plane. Me and the missus had 5% battery each, no place to charge phones and no in seat entertainment. That was a long and painful flight!
I should prob look into it more as we fly to SA most years which is overnight, so a better plane would help the journey.
