You're right : A3 doesn't have an executive/elite bonus at all. OZ does have, a 5% to 20% according to status, but on their metal only.
It does make BA more attractive from an earning point of view. For example, a flight to SIN in I with BA will earn you, as a BAEC Gold, 33,715 miles, while a flight in Business in Z with Swiss, crediting to A3, will only get you 26,972. On the other hand, you should also look at redemption rate. To get one of those business flight to SIN, you'd need 140,000 with BA, while you only need 100,000 with A3. So it's a free flight every 4.15 with BA vs every 3.70 with A3. Obviously, award charts aren't exactly identical and you need to do the maths for your travel pattern and redemption pattern and Tesco addiction, rather than just considering earning rates.
At some point, as A3/OZ and BA aren't in the same alliance, you should consider also how they cover your target area. They overlap partly, but one is bound to serve your needs better than the other.
