i think that Erza is stronger because well natsu's great and all but Erza is probably the only one to be able to defeat midnight due to her artificial eye and Natsu only was able to beat Zero because of Jellal's power up thingy also for the tower of heaven Gray defeated the owl dude Natsu just got eaten and as for battling Jellal Erza was tried and worn out Natsu was not and Natsu would have lost if not for the wound Erza gave Jellal so yes Natsu is strong but i dont think hes stronger then Erza
