1.) I get triple Avios with BA amex on BA flights; don't think that would work if bought through AA.
2.) I'd get stung for a 3% FX fee for $ purchases.

Other reasons that might matter to some but don't really to me:

1.) Impossible to upgrade tickets on AA stock with Avios: don't really care as I usually buy cheap business fares for these messy complex TP runs and even on BA stock, I've never once found any F availability that worked. Even if you do everthing right, it's pretty hard to upgrade using on AA metal using Avios. Cash upgrades at airport are the way to go if you get a good offer.
2.) Someone said somewhere that you get fewer miles on AA, not sure of this is true and think it would be small enough not to matter; it's all about the TPs.

Is there anything else I'm missing one way or the other? Is it easier to rebook on AA stock if AA cancels or makes schedule changes, for example?
