KE wins in every dimension. You will get either the 747 or the A380, but both have fully flat/horizontal seats. The seats are traditional but they have removed rows, so that they are fully forizontal 74" pitch (AF is 62" angled) without any stacking or herringboning. So huge amount of space (but pair seats).
The only advantage of AF could be that it leaves at 1:30pm instead of 09:00pm.
