The award related fees are higher but at least for now, in many instances the mileage requirements are still low. US didn't bump their award levels in the past year like many airlines.

Example:
US - Europe: Y:50K C:80K F:125K
US - N.Asia: Y:60K C:90K F:120K
US - NZ/AU: Y:80K C:110K F:140K

And there's seemingly no mileage limit, meaning you can travel LAX to SYD via BKK, HKG, and SIN if you wanted to and found the space. Oh, and generally a perfect match between what ANA inventory shows available and what US agents can see.

Other than this specific award flexibility (fees notwithstanding), if you value the service level more, go with UA. If you travel enough for 1K, the SWU's and CR-1's are far more valuable than the near-nothing you get from US as a top tier elite.
