Blizzard or Typhoon?

We prefer BB, but it's been a while since we've to TL. We hit the water parks every visit and think the add on to the ticket is worth the extra cost. Unlike our friends from the North who don't appreciate the theming at BB, being from Georgia we rarely get to see the "white stuff" so we really like the theme.
As for the rides BB has or did have (some other water park may have now built a taller one) the tallest water slide in the country and it is always a teen favorite along with many other rides.

One responder here asked about doing both parks in one day. I just read that Disney is about to add direct bus service from one water park to the other instead of only going to resorts or theme park locations. That in itself will save an hour of travel time and make 2 in 1 day much more feasible.
