Only an all-time classic, is all.
It's amazing ( arf! ) when you stop to think about how great Spidey's book was, and for how long. All through Ditko, Romita, Kane and Andru it really was the gold standard.
But it was Conway & Andru that, if pushed, would be 'my' run. Not as ground-breaking as Lee / Ditko obviously, but this was the period where we actually could get American colour Spidey in this country, every month!
And practically every issue was a classic in the making. Take this one, where Petey moves in with Flash, an epoch making event in itself. Add to that a great, tortured villain, and the fact that the neighbourhood is being torn down in a spate of '70's urban renewal, giving Spidey not that many places to swing from, and you have a masterclass in how to do it in one issue.
In that PBS
Superheroes documentary, somebody says that the reason '70's Marvel writers could write so convincingly about New York was because they were all living in the not-so-nice areas, and I'd be willing to bet we're looking at Gerry Conway's old neighbourhood here.
Just an added frisson to an already great story.
