Both shows has a similar concept with "boy-meets-girl" story, where main hero meets a strange girl, who has a superpowers. And also has a similar concept of the world, where there are monsters threatening to destroy humanity and robots that save people.
Other than the obvious 'mechas save the world' theme, both female leads have similar personalities and attitudes throughout the show, and both shows focused on trying to find out about their pasts. Also, a lot of innuendos and implied metaphors about relationships in regards to the mechs and its relation to the main duo, if I can put it in that way.
