Very true. Both programs have their own advantages.
It could, however, be a reason for someone who only wants to use their miles domestically to choose AA as their preferred carrier, provided their schedule and needs fit visiting two destinations on every award ticket.
UA definitely is stronger when it comes to other awards, especially Asia.
