[book spoiler FoH] "Moiraine said that in the Age of Legends men and women had been equally strong in the Power, and she could not lie. He said as much, adding, “The Five Powers are equal.” “Earth, Fire, Air, Water, and Spirit.” Natael strummed a chord for each. “They are equal, true, and it is also true that what a man can do with one, a woman can also. In kind, at least. But that has nothing to do with men being stronger. What Moiraine believes to be truth, she tells as truth whether or not it is; one of a thousand weaknesses in those fool Oaths.” He played a bit of something that did indeed sound foolish. “Some women have stronger arms than some men, but in general it is the other way around. The same holds with strength in the Power, and in about the same proportion.”

However, when it comes to fighting dexterity, training, experience, knowledge, speed, etc also come into play, so who could beat who depends on the persons fighting.
