No one FF program is really better than another for economy class flights, even though AA is probably the best. Having said that, deep discount economy fares on BA earn little 25% or none (CX) in the AA program. If the flights on CX are in a class that earns miles, that may be the way to go. On BA, you can't even join unless you fly an 'full' fare economy flight.
