Well definitely mira. Coz Satan soul's destructive power was unmatched and her spells could defeat fried which was a one-sided match. Halphas is simply op. She could destroy a city and given how she played with satan soul and overwhelmed racer's speed its simply fantastic. Sitri is her strongest maybe(only according to erza) but has shown high power. She single handedly put the garou knights on the run and lucy and happy commented at her overwhelming power. Macro is the curse that mira took over from sayla and its not MAGIC so nakagami armour which could through magic can do nothing to it. Given that erza could not resist kyouka' sensory curse while sayla commented that curses dont seem to affect mira. And furthermore her stamina to use satan soul has dramatically increased. In the GMG arc she used sitri and satan soul twice without so much as a gap and showed no signs of fatigue. Simply erza has shown incredible durability but dont underestimate mira's human form endurance. She was repeatedly struck by sayla in her released form but still survived. So in the end you do get to know who's more powerful. Mira wins but with difficulty
