Back to the OPs question. Those rankings are about right, but the mid-late 80s Campy groups are missing. Those were from top to bottom (and stayed close to that until the mid 90s) :

Record (lots of people call it C-Record, but "C" stands for "Corsa" = road, to differentiate it from "Pista" = track, but the group's name is Record )
Chorus
Athena
Victory/Veloce
Junk (Eucl
id, Mirage, Xenon)

+1 to miamijim's comment about a rudimentary Shimano SIS group (like 105 or even Exage) was better in shifting and braking than any of those, from 1987 to about 1992. Then Campy introduced Ergos. Game over as far as shifting went, but Shimano still did have the advantage in braking for a good decade...
