Despite all the changes, the US programs generally seem to be more generous for economy class travellers than the European ones, and UA's still has that attribute. However, the equation changes considerably if you largely fly Business Class.
The other thing to be very careful of is fare classes - if it's not a TATL flight, then it's quite tricky finding out whether a flight will qualify for UA miles - I do my best but I still find it quite hit and miss.
