We have stayed at both. There are different reasons to like each of them. For your situation, I would consider this...
POR is much bigger than POFQ. Depending on what building you would be in, it can be quite a walk to get to the dining area, pool, boat and bus. There are 4 bus stops at POR, but you still could be quite a ways from the stop.
POFQ has a great pool for the younger aged kids.
With the age of your children, I think everyone would enjoy POFQ because of it's smaller size.
Please keep in mind, because it is a smaller resort, it does fill up faster.
