Besides, I think the Romita era is the one where the characters-or at least Peter and Gwen- got their iconic looks, and things like this make me think that creating characters that were believable as human beings was what Stan Lee brought to the table.
As talented and important as Ditko is, Romita's arrival really saved characters like Gwen and Harry. His "softer" art style helped change the way they were written, since by the end of his run Ditko's pen and "Peter against the world" attitude made them both very pinched and angry and toxic.
