As you said, those are quite different.
os tubing and a steel fork vs 2os+ tubing and a carbon fork.
the geometry chart for the tommasininis beyond worthless and the Battaglin is custom, so thats a significant difference.
the cromovelato paint on Battaglin frames is amazing.
the massivd lugs on the Portofino look cool in some instances and plump in other instances. I think when they are chrome it's better?...jury is out.

Interesting couple of frames you have narrowed your options to. Whats the reasoning for these?
...i always enjoy hearing how someone came to narrow the seemingly endless list of steel frame options.
