My criteria are slightly different for an O&D airport versus a connection hub. For O&D I care about how efficient transit/parking and security are. It's nice to have good food options and lounges but these are not as important. Basically, I emphasize quick in/out. For a connecting hub I don't care about security or transit as I'm not using them. Food, lounges, and other amenities become more important, especially on longer connections or between long flights.
