Male companions VS Female companions, Who wins in a fight?

The fight will be on a Arena, they will all be at their highest levels and have the best possible equipment, all weapons, skills and spells are allowed and each person can use two big healing pots

I tried to put the best ones for each sex, though you are free to state if another companion could be better for each team.

PS: It's very difficult to edit on the phone, so pardon me.
