CrossWorld Buzz: Good. The WATER-H2O rebus theme is a cut above a standard Sunday theme and the fill is fine.
CrossOver Buzz: Also good. The real-world zing of answers like WATERGATE SCANDAL and BATTLE OF WATERLOO matters more to real people than it does to puzzle people. On the other hand, the semi-intricacy of the theme that makes it a winner for insiders makes it kinda confusing for real people. The two factors are more or less a wash I believe--thus the same good rating for both CrossWorld and CrossOver.
