I liked TL better, especially their wave pool and lazy river.
ETA: BB also had a nice lazy river, and the Toboggan races were fun. But their wave pool was WAY too much for me because I'm a tiny girl and not a strong swimmer. It just wasn't enjoyable for me because you couldn't just sit and let the waves go around you. They had lots of exciting water slides though, but I didn't really go on them(not my thing).
