Executive Floor room or "normal" room, same price at different hotels..

I have two Reservations:

Hilton Mission Valley and Hilton San Diego Airport/Harbor Island for the same price. Should I stay in Mission Valley with my upgraded room or stay at the airport hotel and hope for an upgrade? I have stayed at Mission Valley before but not the airport, and the airport Hilton is currently being remolded.

I'm leaning towards Mission Valley but the airport has better views..
