put simply - males in general play more masculine, and females in general play more feminine.of course this is as variable as femininity and masculinity in people's personalities - so you can end up with males playing more feminine, and females more masculine.
I would actually say, from those performances I've seen, that if there's a way they can be stereotyped, that females are more moderate. Not necessarily dainty, but it seems as if males play both more loudly and more softly. Females are inclined more towards clean playing, I think. Granted, these are overbroad generalizations, so don't take them as any more than that.
