Gil Kane and Kurt Busiek seem to have something in common. They had good runs on Spider-Man, but I have the impression that it's not their best-regarded work.
For example, Kurt Busiek is rated as the 15th best comic book writer ever by CBR readers, but doesn't make the top ten of Spider-Man writers in a CBR poll. His run has been collected in an omnibus, a relatively rare distinction.
Kane does better on the list, although it's his highest showing (the Newsarama Top Ten list doesn't include him.) He has the advantage of illustrating one of the most famous Spider-Man stories ever, but the CBR list of top Spider-Man artists has him surpassed by two guys who didn't make the Top 50 comic book artists like (Mark Bagley and Ross Andru, who probably should have made it but that's a different story.)
Is Kane and Busiek's Spider-Man work overlooked for whatever reason? If so, what are the reasons?
