One thing to factor in here: BA's CPH flights go from LHR T5, so if picking AA for the transatlantic you would need to transfer T3<>T5 which is certainly more of a faff than T5<>T5. The onboard products are largely similar, so it may come down to a choice between free seat selection vs easier transfer.
