There is Green Flag as well.
The wife and I are trying to decide this at the moment as she gets free AA if she upgrades here bank account and I get free Green Flag if I upgrade mine.
The only difference I can see is that Green Flag covers the car, whoever is driving, but AA are offering to cover the person (my wife and we have to pay extra for me) whatever they are driving.
Might be worth checkiong what your bank account offers:
LloydsTSB - AA
Barclays - Green Flag
