Go for the seats in the front. Nobody ever walks by. I also prefer clockwise left to right as that seems to be the direction of the food cart.
I agree that CX beats the heck out of AA in all cabins. In F I prefer AA's Bose headsets and DVDs provided on non-777 flight but overall the _only_ choice is CX, if for nothing else than to get a flight attendant that cares.
Another neat thing on CX: you can order food any time. You can even get leftover dinner items!
