You would earn 180 TP's for a return JFK-LHR in WTP. Three of those would get you BA Bronze, not quite enough for BA Silver (oneworld Sapphire) which would provide lounge access. It would earn you just over 30k EQP if credited to AA which would get you close to AA Platinum. If you travel on AA domestically in economy AA status is probably more beneficial than BA Bronze.

However 4x WTP JFK-LHR would get you either to BA Silver or AA Plat, so it comes back to what to do with the status you have.
(Note you could challenge up to Plat on AA with one WTP round trip, hence earning double spendable miles from then on.)
Avios are okay for US domestic economy awards, depending on distance, whereas AA miles are better for TATL redemptions. Avios are good for upgrading from WT+ to Club; however with AA miles/metal you could buy cheap economy seats and upgrade to business with miles and co-pay and probably end up in about the same place out of pocket, given the need to buy WT+ with BA in the first place (no economy - business direct upgrades, only one class of service.) Also no BA fuel fines on award tickets using AA metal.
Given the devaluation of Avios I'd probably stay with AA, look at challenging up to Platinum, and go from there.
