American:
Has an award chart, like United
Seems to be a stickler with carry on luggage sizers, though other airlines sometimes do this.

Delta:
More planes seem to have IFE than AA

United:
IFE seems not quite as good as DL but not much different. I see it in more aircraft than AA.

Hubs use by individuals vary according to one's location and the airlines' schedule so I don't want to complicate this thread. I do have favorites, like MSP over ATL, IAH over DEN.

If there is no difference, then I would choose based mostly on schedule and fares with a very slight preference to one airline because of frequent flyer program participation.
