Justine. But the final against Mauresmo would be close. Amelie had a wonderful tournament, convincingly defeating Myskina and Capriati.
And her stats were certainly impressive. For instance: A winning percentage of 100 against Laura Granville on her 1st serve (28 points).
However, she did fold badly against Serena, while Henin put up a better fight vis-a-vis Venus. If I'm not mistaken, they have hardly played each other in the past, so we can't speak about 'ownership'.
Henin didn't impress insanely in this tournament either, only overcoming Dementieva and Seles by narrow margins. But I think she's a better player than Amelie in most aspects.
And when Mauresmo is under pressure, like she would be in a final, I see her big grass weapon, the thunderous 1st serve, deteriorating rapidly.
