thanks for all your help.

so the way i see it i would have the following benefits:

AA

-225% miles in busines (w/status)
-free upgrades in the us
-8 swu's (only on AA right now)
-no fuel surcharge on awards / is this also on BA awards?
-no lounge access in the us on domestic flights

BA
-225% miles in business (w/status)
-higher awards
-better service during irops / more opups on BA metal
- lounge acces on domestic US filghts


I do prefer usually to keep status on the home airline but AA is looking better due to the upgrades / lower mileage requirements with the same earning rate.

am i getting this right?

you guys are awesome!
