There's no way to know. Because training and equipment aren't everything. This is the problem when you take generalities and try to apply them to everyone, you end up missing out on the outliers. The woman may be more intelligent and take to the training better, or have better reflexes, or a million different scenarios where the woman is the better candidate.
Applying statistics to whole population is foolish, which the Qunari despite all of their obvious flaws is not.
If you want the best, you look for the best, you don't let statistics change that.
you are over thinking a rather simple question, and going beyond the parameters, I am talking two equally matched opponents in gear and training (for example intelligence would be a rather negligible factor in this, being smart ain't gonna help you take a blow any better)
Humans (and primates in general) are sexually dimorphic, the males of the species are larger and stronger due to more testosterone and, usually, a lifestyle that is more physically demanding.
And statistics are important in many ways, and I don't think that really needs explanation. Furthermore, the qunari are built precisely around the average, not the exemplary, Solas spells this out rather bluntly in banter with Bull.
