DC and Marvel were both known in the 60's for overpowering inkers, with DC's toning things down to a mild, dull "house style", and Marvel's each going in their own different directions.
It's funny, being a DC fan, and largely looking over the fence at Marvel, my opinion is completely the reverse. DC was full of distinctive pencillers and distinctive inkers, while Marvel (after the departure of Ditko) seemed to have that dull house style. Artists who were very distinctive at DC and I could easily tell apart--Jim Mooney, Ross Andru, John Romita, Gil Kane--became very similar once they went over to Marvel.
As well, I found Spider-Man (post-Ditko) really invited a dull, generic look. Unlike someone like Batman, the character didn't invite a variety of interpretation. At least with the Kirby characters there was a degree of excitement--even if every other artist at Marvel was pressed to copy Kirby's style on those characters.
If I didn't see the credits on Mooney's Spider-Man work, I wouldn't have known this was the same artist who did so many great DC comics. Whereas very early on, I learned to tell the difference between all the pencillers and inkers at DC--who often weren't even credited on a story. And DC had all those idiosyncratic artists like Joe Kubert, Kurt Schaffenberger, Mike Sekowsky, Carmine Infantino, Bruno Premiani, Bob Oksner, George Papp, Curt Swan, and Wayne Boring.
The big DC inkers--Sid Greene, Murphy Anderson, Joe Giella, George Klein--I could spot a mile away for their unique styles. But I would admit that each of those inkers tended to overpower the pencillers they worked over to a certain degree.
Being a much bigger tent, employing many more editors and artists, DC had a wide variety of flavours--whereas Marvel had a lot of the same Lee/Kirby/Romita remixes. But I'm sure if I had been a more devoted Marvel follower, my opinion might have been different.
