Personally, I think this is when Italian racing bikes left their artisan roots in ways that were mostly negative - much less hand work went into the frames. They became much more stylistically similar overall - everybody had the same Microfusione lugs with cast-in names and logos. So as a whole, they hang together more aesthetically, with the main difference being paint and graphics and branding - which accordingly began to receive much more attention from builders with fewer ways to stand out from the crowd. This means much less reason to choose one Italian brand over another, aside from occasional departures from the standard stage race geometry that might suit a particular rider. That's why "name chasing" makes so little sense when it comes to 80's Italian racing bikes.
On the other hand, another way to stand out from the crowd was to do something dramatic design-wise - Colnago led the way in many respects in this regard with its shaped tubing. I give Rossin credit here, as they managed to create frames that are aesthetically dramatic in ways that sometimes allow them to stand out from the crowd.
