AFROTC is much more straightforward. It also has a lot more pilot slots available. If your daughter can, try to go the AFROTC route. Also, while its true that you may get RPA or ABM, when I saw the accessions for each rated AFSC (flying jobs) for 2016 most ABM slots were filled by Academy grads. There are way more pilot/CSO positions than RPA positions too. So at the end of the day, your daughter has a good chance for being selected for either pilot or CSO.
In case you don't know the acronyms:
ABM = Air Battle Manager (these guys coordinate Air Battles)
CSO = Combat Systems Operator (Navigator)
RPA = Remotely Piloted Aircraft (Drone Pilot)
