I've stayed at all 4 locations; here is my opinion.
AKL/Jambo. If we can afford it (BIG if), I stay here and ask for a partial savanna view room. I love AKL, it's my favorite place to stay anywhere, not just WDW, but it's expensive. People complain about the length of the halls at Jambo, but honestly... you have to walk a decent distance to ANY hotel room in Disney, so I'm not sure why AKL gets the majority of the complaints! I go to AKL every Disney trip, just to sit in the lobby for a bit to absorb the serenity and ambiance, or to enjoy an adult bev at Victoria Falls. Yes... I like AKL that much that I'll take time out of a park day just to visit the resort.
SSR- DH and I are staying here for 4 nights in January. I don't find the resort or the food/bev options very exciting, but we got a good rate by renting DVC points. We stay here mostly when we are doing a non-parks trip, as we enjoy the proximity to Disney Springs restaurants and bars.
CSR- I LOVE staying at CSR! Now that Three Bridges is in the middle of the lake and there are several bridges across the lake, it doesn't seem that big. The resort is beautiful! I also like that there are multiple restaurants, lounges that stay open later in the evening, etc. Last time I splurged on a preferred location and was a 5 minute walk from the bus stop.
POFQ- We like POFQ well enough, and it's sometimes a choice when DH is traveling with me as he doesn't enjoy crowds. I mainly choose POFQ when I want a small, quieter resort. My sister lives in NOLA so we aren't terribly impressed with either the food court or the beignets at POFQ, but it's a nice little resort with great bartenders at both the pool bar and ScatCats.
