I bought a bunch of Marvel Tales before I had any conception of what a 'reprint' was, so I felt that too. I did notice a difference between the ASMs and Spectaculars I was buying, and the Marvel Tales, and I actually preferred the older stuff. I'm not sure exactly why, I guess there was just something about Romita Sr's art and the accessibility of the stories that drew me in.
My earliest exposure to Spider-Man was in the Ross Andru interiors/Romita/Kane covers days. When I went back and found the Ditko stuff, it was pretty alien to me. It seemed so primitive in comparison. I definitely have more of an appreciation for the Ditko stuff now, but it'll never be the Spider-Man for me. Kind of ironic, I know.
