We've been to both. Each has its own unique attractions. I personally like the theming of Blizzard Beach better, but Typhoon Lagoon has the new water coasters, "Crush n Gusher," which I haven't experienced yet. It also has a wave pool that makes six foot waves; it also has a shark tank that you can view from a submerged boat or, if you feel so inclined, swim with them; BB's wave maker just makes moderate swells, not waves. Both have lazy rivers, and both get really full in the summer, often closing when they get full. The best thing is to go early and get your spots. Both are really well guarded so your kids will be well taken care of!!!!!!
