We prefer TL over BB however my kids are older (14 and 11). We can spend hours in the wave pool, the lazy river, and sliding down Crush n Gusher. We all love the lushness that the park has, BB seems too concrete to us. The family slide at BB is the one thing that we really enjoyed at that park, and my DH really liked Summit Plummit, but other then that we would much prefer going to TL. But on the flip side, I do agree with the PP that the wave pool at BB is not as intense as TL, so for your son's age, you may want to consider it for him.
