I would probably choose POR, because even though I loved our stay at AKL, I want to try all the resorts at some point.
Otherwise, if my budget permitted, I'd pretty much always go with a deluxe.
AKL has more dining options and a very cozy feel to it. Everything is in the same building, so you don't have to worry about rain as much.
They both have all bus transportation, but AKL only shares with AKV, so there are only two stops.
AKL is literally right around the corner from the Animal Kingdom, whereas POR is probably about equidistant to all the parks. If you plan to spend a lot of time at the Magic Kingdom, you may prefer POR.
If it's not a surprise, ask your daughter. She may have an opinion one way or the other. I don't think you can go wrong with either.
