In high school & seminary I had male teachers & female teachers for various subjects, including chumash, navi, halacha, and hashkafa. Some of the male teachers were good, others less so. In high school we had a hilchos shabbos class with a local rav who is a major posek. I’d say he was probably the best halacha teacher I’ve had, male or female. Some of the male teachers tended to have more trouble controlling the class than female teachers.
In college most of my professors were male, but the female professors we had were well-qualified & generally better teachers.
