Certainly I would say that volumes 7 and 8 would be almost complete duds (albeit entertainingly quaint) but volume 6 would be a classic.

Glad you said "almost" because if Iron man volume 7 were to include say issues 25-35 and Daredevil 73, it wouldn't be all duds. The Nick Fury / Zodiac crossover with Daredevil was a bit of a favourite of mine at the time. Firebrand makes his debut in #27 and #28 has a great Controller cover / story.
