Love them both for different reasons. POR is a beautiful resort, with lush landscaping. It is so wonderful to just walk around and be immersed in the whole thing. It's main pool area is a ton of fun. The rooms are fine...depends on whether you prefer the more 'rustic' feel of AB or the more 'formal' feel of the mansions. It can be a bit spread out if you get a room in a more distant building but that just means a nicer, more relaxed walk for coffee in the morning.
And being able to take the boat to DTD is great. The buses do make multiple stops within the resort before leaving for the parks.
Pop is bright and colorful. Really over the top theming. There isn't much in the way of landscaping though. But it is a lively resort. I did enjoy walking around the outside of the resort....fun things to see along the way. I did like the food court area..yes, it is loud and sometimes rowdy. But if you can be there at off times, it's much more relaxing!! The buses are very good..you don't share with any other resorts. Once you are on the bus, you do to the park. The main pool is pretty but there is no slide...none of the value resorts have slides. I did find the quiet pools to be nice since they were seldom very busy. Since you've stayed at Pop, you already know all this though.
I guess it all depends on what you want in a resort. Relaxing? More adult? Go with POR. But, if you want bright and happy and in your face? Stick with Pop.
I say go with POR. You're not buying it...you're just staying there for a brief time. If you decide you don't really care for it, great. No need to stay there again.
