I have to say the Ditko run, even though it was the Lee/Romita, then the Conway/Kane, and then Wein/Andru that I read when they first came out, though very sporadically with the first two, Romita and Kane. I did read the death of Gwen Stacy, though. I was a bit too young to read the Ditko issues when they came out., but when I read them in reprints in the 70s (many of them in those digests from the late 70s) they immediately became my favourites - though by then I no longer had my Romita and Kane issues to compare.

This just reminded me of a question I wanted to ask: was Romita's Peter Parker too handsome and well-built to convincingly play the downtrodden nerd? Or had the character grown out of that phase by the time Romita came along? I haven't re-read any of these issues since the 70s, so my memory may be at fault, but I think that by the Wein/Andru run that was certainly true - Parker was a competent, respected college student, though of course always getting into problems because of his secret life. But Romita came right after Ditko, there must have been a bit of a transition period at least. Later artists followed the Romita visual model, I think, certainly Andru did.

I took the question to refer to the Amazing Spider-Man series, but I also read the Spectacular Spider-Man for a few early issues and Marvel Team-Up when the guest character or artist took my fancy. The good Team-Up issues were more fun than the best Amazing in the 70s.
