I've stayed at both, and enjoyed each one. Personally, I prefer POFQ for its size and the fact that the WDW buses usually pick up there before continuing to POR (when I was there last week, the exception to this was the bus for Typhoon Lagoon/DTD, which picked up at POR first and then came to POFQ).
POR has a larger food court, a table service restaurant, and quiet pools, which are not available at POFQ, but at POFQ the pool is centrally located, the food court is sufficient, and I can be pretty much anywhere in the resort in just 2 or 3 minutes. If I want table service I can walk, take the boat, or a bus to Boatright's at POR.
I guess it really depends on your priorities and family situation as to which resort would work best for you.
