I've been to all of three of them and they each have different things I like with one or two things I might not like,I'm a big waterpark guy, been to 15-20 different ones and for the most part like them all.If I had to give some pros and cons to each park I would say both Disney parks are bigger,TL has the most shade of either three but has the worst selection of slides,I love Crush n Gusher but the rest are very mediocre.BB has good slides but I don't like the way the park is laid out that you continuously have to climb the same stairs since all the slides are on the mountain,the chairlift is great but only gives you access to 2 slides.Both Disney parks have good lazy rivers.Aquatica is laid out more like a traditional waterpark,has good slides probably better than TL but not quite as good as BB,Aquatica has a fast lazy river that's probably the coolest thing at all three parks as well as a smaller traditional lazy river with windows that show the pool with the dolphins and another one with tropical fish.As far as the wavepools I would put Aquatica at the top with TL just below and BB third,Aquatica has two traditional pools,TL has a big one with the non traditional big wave and BB is smaller and the least impressive.TL has the shark reef which is very cool and Aquatica has the dolphin Plunge slide as well as some animal exhibits.Theming is great from all three parks but Aquatica probably has the least shade but a lot of palm trees.Aquatica wins food options by a long shot,they also win merchandise and clothing by a bigger longshot,it's amazing how much more Aquatica clothing they have than at the Disney parks which mostly just carries regular name brands,even things in carts throughout the parks like carts with books which I don't remember seeing anywhere at TL or BB.In the end they're all very good parks so I would suggest that you do visit Aquatica.
