We have Hopped just about every pool at Disney, inc SAB before it was taboo. Our kids are 6,8,12, they enjoy the Poly pool, but as an adult I wish they had a hot tub. Great location. The Coranado is nice. Same story as Poly, great pool kids love the "cheetah slide", good place for parents as they have poolside bar service and a hot tub. The down side is it's a little bit of a hike from the bus stop. Wilderness lodge is also awesome especially for an evening swim/soak.
Those are probably our top three. BW is good, but you should always call ahead to check availibility and we have have found that BW is often closed to hopping even when the numbers don't seem to justify it. We also enjoy going to PO, both FQ and Riverside Good pools, nice theming, slides, poolside bar service and excellent food courts close by. I believe PO FQ is closing for awhile though.
