Wanger:
My 2 cents....
Wet and Wild is fun...like any other Wet and Wild etc. across the country. Good slides, but not especially "Themey".
WaterMania is like you'd find in any small town. Not esp. nice or pretty....I used to like it when I was a CM as we could get tix for like 5 bucks or so....but it was pretty good bang for the buck. Very "City Pool" in the theming.
Typhoon Lagoon--best atmosphere/theme, IMHO (I love the whole tropical island theme thing). Not the most slides, but some cool features, and WHAT a wave pool!!!
Blizzard Beach--also very heavily themed...with quite a few more rides/slides than TL.
Depends on what you're looking for/what's important to you. If you're on a shoestring, I'd do WM. Thrill seeking Teenagers? W & W. Heavy themes important/the 'Disney' feel important? TL or BB.
YMMV.
