BA or AA is another possibility, but most of my flying is on routes where Oneworld isn't a very good choice, and both BA and AA have crappy mileage for CX economy class.

I've also taken a look at eight different Star programs, and I've taken a hodgepodge of Star Alliance flights (on SK, LH, LX, TK, JK, CA, TG), plus some QR flights, that I may take next year, and those flights would give me the following mileage:

OZ: 36,533 miles
A3: 36,363
UA: 35,414
LH: 35,314
US: 31,701
TK: 29,624
TG: 27,220
AC: 23,798

It appears to me that my best choice would be to stick with A3 on all flights where they give mileage, which would give me 36,363 miles, and put the other flights (such as QR, which is not part of the A3-program), into UA (11,267 miles) or US (6991 miles).
