Mostly good!
Thirty years in this business and counting, so far only one really bad femail.
On the whole all ( but one) the women that I have worked with have been well above average both in professional skills and ease to work with, this includes a number of Avionic technicians and only one airframe & engine technician.
I wish the numbers were so good for the men, the worst of who had ego's the size of a small planet.
