I'd go with the AA 77W and I think I'd do this over any of the BA Club World options. It's got to the point where the only times I use BA across the pond in Club World are on the A318 and the B747 (upper deck). If I'm not on those flights then I'll go with another carrier (usually AA since my first entry point in the US can usually be one served by an AA 77W).

I must admit I've not flown Club World on the A380. I've seen both decks' Club World cabins when I flew in First though but what I did see left me with no real desire to want to try the Club World cabins on that aircraft.
