I think you would find quite a few of us prefer EVA over United. Problem is you can't buy their tickets on United.com except award tix.
ANA is also very nice, but you have to be careful, so of the connections from Japan are on older angle flat or barca lounge planes (I haven't flown them in a while, so they have been phased out)
I fly UA for the miles accumulation for Vacation, No one else has a network like Star Alliance and I can live with UA for business so I can vacation easier with my family.
