Gary,
I haven't tried AA with their new business class seats yet, but from what I hear, BA's club world seat is definitely better even though they are older! Expect the new beds new year.
BA's seat is better, entertainment is better and BA's arrival lounge is the best there is!
Also, AA flies Airbus and BA flies 777 or 747-200 depending on the flight.
