Wondering if anyone has opinions about which of the OneWorld members would serve me best as an NYC based flier?

The obvious choice is American, but wondering if might be easier to make higher status with another member.

For example, on Swiss, for a non-resident it only takes 70K miles to qualify for their highest (Gold) status which is (I think) is equivalent to EX Plat with AA.

Would I still qualify for unlimited upgrades when travelling AA domestic?

My flight profile:

Business, usually full-fare economy (ugh)
2 per quarter to Finland (Finnair obviously)
Once every six months to Beijing, Singapore, Sao Paulo
Minimal domestic travel

Private, cheapest available
2/3 trips per annum usual international

As you can see, I'm already AA plat but with the segment requirement could be difficult given mostly int'l segments.

Thanks for your thoughts.
