I think it depends on what you want. Overall, I think the theming and the wave pool is better at TL and the new ride (Crush Gusher) is reported to be great. BB has more and a larger variety of slides (including two enclosed dark slides which are a kick), so if you're really into the slides, BB is probably a better choice. Personally, I think the coral reef snorkel is way over-rated, but that's just me.
