AA.com can only show awards involving the following carriers:
AA/US, AB, BA, AY, QF, RJ and AS/HA.
So, for Europe-US, AA.com will cover the majority of options and is better with multi-segment award searches. One notable omission for TATL is IB.
However BA.com covers all oneworld carriers (bold is not shown on AA.com):
AA/US, AB, BA, AY, QF, RJ,
CX, IB, JL, LA, MH, QR, S7, UL, JJ
So for those who head east as well as west, BA.com has far better coverage.
